Michael Valentine powered a lot of transcontinental runs (Cannonball) including Ed Bolian's landmark 28:50 run. He will be missed; he's a hero in my social circles.

  Not for me. I find radar detectors wrong. Speeding has risks, mainly for others, and pollutes. If you want to arrive earlier, leave on time.

    We have a right to know what radiation is being radiated at us. It's no different than sight, just in a different wavelength. It's what we choose to do with that knowledge is the subject of the law. We have a right to detect what is bring radiated at us.
    - hunter2_ 2y ago
      Morally, I agree 100%. But legally, detection is banned in some jurisdictions (Virginia, Washington DC, most of Canada, etc.) so it's ambiguous to say "we have a right" without at least defining which population and which definition of right.

      I ham a ham radio license and should probably know this stuff, but I don’t play near the edges where I’d ever need to worry about the details. It seems nuts to me that it’s illegal, anywhere, to notice what radiation (technical sense) is around me. “Hey, watch out, in Kentucky it’s illegal to see orange” is about as logical as anti-detector laws. You’re pointing an emitter at me and I’m not even allowed to know? That’s crazy.

    There are places where police have been known to abuse ticketing for speeding. Estelline, Texas is one. Brookside, Alabama another. https://www.atlantanewsfirst.com/2024/08/05/i-was-cash-cow-i-georgia-cities-accused-using-police-revenue-generators/ https://www.atlantanewsfirst.com/2024/08/05/i-was-cash-cow-i... I know a section of 322 in PA was once so abused, that the local police lost jurisdiction and the State Police took over patrolling that strip.

      Macks Creek, MO was locally famous: https://en.wikipedia.org/wiki/Macks_Creek,_Missouri https://en.wikipedia.org/wiki/Macks_Creek,_Missouri They got 85% of the town’s revenue from speeding. There was a drop from 55 to 45 well away from anything where there was any obvious reason to slow down. If you were doing 46 when you passed that sign, you got a ticket.

    All the economic evidence of risk homeostasis, and general consistency around the subject, suggests your preferences writ large are at odds with and part of a battle with human nature. That's fine for an opinion but the implications are pretty dire for interventions - like squeezing a balloon there will inevitably be side effects. Not trying to diminish the consequences of said risks. A successful strategy probably involves accounting for and maybe even improving the competing economic interests rather than picking one and stifling it.

    I find speed limits immoral. The idea that broad swaths of New Mexico or Texas or Arizona should not be American Autobahns is reprehensible.
    - bluGill 2y ago
      Realistically they are - the speed everyone drives (5 over the posted speed limit) is about the speeds most people are driving on the no speed limit sections of the Autobahn.
  - JohnMakin 2y ago
    I use one but I do not usually speed - because most police cars in my state have radar signals on at all times, it basically tells you if there are any police cruisers within ~1 mile. I believe cops are dangerous and unpredictable so this is useful information to me.

        kstrauser 2y ago
        I hear ya. If someone with skin a different shade than mine says they’d prefer not to talk to the police, I’m not going to argue. About 10-15 years ago when everyone got cameras was when it changed in my mind from something you heard about too often, but randomly, to seemingly every freaking day with hard evidence to prove it. I know it’s been going on a lot longer than 10 years. I think it’s kind of like rogue waves. The people involved had been telling stories forever about the things they’d seen. Now that we have recordings everywhere, what do you know, rogue waves all over the place. And people who’d experienced them are like, yeah, we’ve been trying to tell you for ages.

    > Speeding has risks, mainly for others Intentionally driving slower than traffic flow, causing impediments and angry drivers to pass you on the left and right is far more dangerous. E.g. the left lane campers and road vigilantes. > and pollutes. You can't speed in an EV?
    - hunter2_ 2y ago
      Regardless of EV/ICE, the amount of pollution from tires is directly influenced by how much traction is being utilized. Excessive acceleration, deceleration, hard cornering, weight, etc. all lead to excessive tire wear and EVs tend to have elevated figures in all these categories (except cornering I suppose). Instant torque is fun (so unnecessary acceleration is common), braking is regenerative (so minimizing braking isn't as critical to range), and batteries weigh a lot. Therefore, tires shed more quickly. As for pollution from burning fuel, yes EVs are much better, but there's still some fuel involved upstream in many cases, and the drag from high speed results in less range which means more fuel for a given distance.
    - kstrauser 2y ago
      I’d probably agree with you over a beer about the former. The latter? EVs don’t pollute more at higher speeds (modulo the tire thing), but they use their charge faster and have to recharge sooner, and whatever’s providing that electricity uses just a little more resources than it would otherwise.
  - hmmm-i-wonder 2y ago
    'Leave on time' OK. I have a 1.5 hour drive. I leave on time. I run across a driver doing 10mph under the speed limit. I'm late. OK, I leave 10m early. I run across an accident. I'm late. OK, I leave 15m early. I run across a surprise document check and the officer is extra chatty. Combined with the traffic choke point I'm late. OK I leave 30m early for everywhere I go. I'm still late or early and never on time because I can't moderate my speed because someone thinks its 'risky'. Finally, the pollutes more argument doesn't hold up. Just because you have an 'eco' car doesn't mean its economical at traffic speeds. The safest way to drive is maintain the flow of traffic and be predictable (i.e. not slow and no unsafe hyper-mileing maneuvers), and suddenly cars that aren't underpowered microboxes are using less gas anytime you aren't doing 30mph in a city at constant speeds.

  Playing childish racing games in regular traffic at the limit (or beyond) one's abilities deserves absolutely no respect there. Radar detection enabled much more of this, and countless innocent deaths down the line. They say speak only well about the dead, I'd say speak of them as they deserved, each of us builds our own legacy.
  - geetee 2y ago
    I suspect most users are not racing. They're probably driving a comfortable 80mph in 65mph and just don't want to get a ticket for a completely reasonable speed in a modern car.
    - xhkkffbf 2y ago
      Around here, the problem isn't the people going faster than the speed limit. The problem is the driver who absolutely must go 10, 15 or 20mph than the other cars. The weaving and dodging is so dangerous. It's one thing to risk your own life. These people are risking everyone else's by zipping around them.
      - hmmm-i-wonder 2y ago
        Anyone 10+ mph outside the flow of traffic in either direction, combined with overly aggressive or overly cautious moves (i.e. unpredictable compared to other drivers) are dangerous. Unfortunately you can't convince half this group they are part of the issue and the other half doesn't care.
        bradlys 2y ago
        What I worry is the skill of drivers who think going 10mph faster than the flow of traffic is dangerous. You pitch 10mph speed difference as if Louis Hamilton is out on the road flipping cars left and right.

  Same question but about guns.
- techjamie 2y ago
  The US government did a study on highway safety impacts from radar detectors in 1988[1]. While they were able to determine that the presence of a radar detector increased aberrant braking, none of that aberrant braking caused a collision or seemed to be inherently unsafe to other drivers, and also the amount it was observed was statistically very low. They weren't able to determine what the effect was on if a radar detector resulted in more speeding because that was too complex to study though.

I remember the ads in old Car&Track and Road&Driver magazines at the doctor’s office. They always had a veneer of illegality to them, even in states where they were legal. Funny how something like Waze doesn’t. I wonder if it’s that Waze is just the technological equivalent to the oncoming driver flashing their brights at you.
- ryukoposting 2y ago
  I remember thinking the same thing as a kid reading C&D magazines at the doctor's office. I think they showed up in PopSci a few times too. "wait, this is allowed? Cool!"
- neilv 2y ago
  There was also at least one recurring ad for a purported radar jammer. Either in the car magazines or the electronics ones. It might've been "sold in legal kit form".
Workaccount2 2y ago
The primary reason most people own radar detectors is for bullshit speed limits and speed traps. Very few are people looking to street race or be reckless drivers.
JSR_FDED 2y ago
I remember my Valentine V1 fondly. It was so clearly and immediately better than all the other radar detectors. Knowing where the signal was coming from was a game changer. I’m not saying speeding is good, but when you’re on the road a lot and are a responsible driver there are definitely places where you can safely exceed the speed limit and where it feels like the police see enforcement as a fundraising opportunity rather than a safety issue.
- toomuchtodo 2y ago
  I purchased my first one in the early 00s, and while I don't use it anymore, I have kept it because I love the engineering that went into it. I also had the opportunity once to talk to Michael on the phone, but did not know it was him at the time. I was inquiring how to get data off the ext port to correlate with GPS data, before Waze reporting was a thing (I was trying to create a historical speed trap map in my locality). He was knowledgable, but also patient and kind with my unsophisticated questions. A good engineer has left, that's the story, and that is sad.

Police still don't have the radar detector detector.
- antonkochubey 2y ago
  They do - Spectre Elite is the most common RDD around. However, it only detects low-quality and old radar detectors, newer ones are much harder to pick out since they don't emit noise on their superheterodyne frequency.
  - bradleyy 2y ago
    Also, in an ironic twist: Uniden makes the radar detector detectors... and radar detectors which are immune. R7/R8 for the win!
- bluGill 2y ago
  Most places radar detectors are legal. Several courts have even said that the purpose of radar is to slow people down and so radar detectors work just as well as traffic tickets (this was years ago - I'm not sure what the latest case law is) and so you can't make them illegal. The FCC also generally says receivers are legal (again I haven't checked in 25 years so I'm not sure what the latest is). Radar detector detectors exist and are used in places where radar detectors are illegal. As others have pointed out they are limit used against modern radar detectors.

> The automotive industry has lost one of the great saviors of speed. The article glamorizes speeding. Here's one reason not to: Imagine a speeder hitting someone, and the difference between the innocent person being OK, and being disabled/killed, was the speeding. That's not hard to imagine, and seems to be a frequent occurrence in the US. Another thing to imagine: Imagine that everyone obeyed speed laws. Wouldn't there then be more pressure to make the laws more sensible? Instead, we have dangerous speeding by random people, who feel justified in it, and a ton of people individually and unilaterally trying to apply their own judgment of what speeding of theirs is safe for others. Personally, I sure don't want the stupidest and cockiest people deciding what's safe for 'themselves', and applying it counter to the expectations of imminent victims. When we normalize speeding, that's what we get.
- sokoloff 2y ago
  When we normalize 55 mph speed limits on roads where 80 mph is completely reasonable, that’s also what we get: plenty of people breaking a bad law. (If over 95% of people break that law, it’s clearly not codifying what behavior society expects/demands of its members.)
- crazydoggers 2y ago
  The problem you’re ignoring is that there are many places around the country where speed limits are set unreasonably low with the intention of collecting revenue. Until we seperate speed enforcement from revenue collection, then speed limits won’t be about the science and engineering or what is safest for the road, but what is collects the most revenue. I’ve witnessed firsthand a major roadway whose speed limit was lowered from 65 to 55 arbitrarily, along with a jump in enforcement. The road is definitely less safe in fact, since I’ve noticed people on their phones more as the lower speed gives people more confidence. The people who speed dangerously and no speed limit will stop, now drive more aggressive around cars with greater differentials in speed. One time I drove behind a women who I could clearly see had her phone propped up on her steering wheel. She and others driving irrationally or dangerously but at or below the speed limit drive right by the police. At one point when I was stopped for going 60 and given a warning, I asked how come they don’t stop people driving dangerous or on their phones. He’s response was the “laws didn’t let him”. I’m assuming he really meant they can’t reliably collect fines for it since they can’t prove it in court with a radar detector. > Personally, I sure don't want the stupidest and cockiest people deciding what's safe for 'themselves', and applying it counter to the expectations of imminent victims. When we normalize speeding, that's what we get. The safest is supposed to be 85% percentile of speed on a given roadway. Many places have this specified in the books at a state level, however, after doing some research on that years ago, that’s almost never followed locally.

With many (non-police) cars now having radar for collision avoidance, are radar detectors still useful?
- hunter2_ 2y ago
  I only happen to know because I bought a slightly used car in which the first owner had an Escort Max Ci professionally installed. Sensor in the bumper cover, display and controls mounted to the dash with hidden hard-wiring, quite nice. There were a ton of false positives from non-police sources at first, especially Cadillacs if I recall correctly. Then I learned how to disable alerts on all the bands except those known to be used in the places I do most of my driving (2 states) based on websites that specialize in such information. I think I reduced it from like 30 slices of the K band down to about 6 or 7. Problem solved! Granted, it introduces the possibility of encountering police who use bands I've disabled, but I prefer that over a bad SNR. Now I see a cop for about 1/4 of the alerts which is pretty nice. Visible line of sight is often not until the alert has been going for sufficient time to acknowledge.
  - OptionOfT 2y ago
    I'd go and double check whether the sensors in your bumpers aren't laser jammers. The Escort Max Ci 360 (not sure if there is a non-360 version) has laser jammers, and that is what those modules are in the front and rear bumper. Radar is easy to detect, but illegal to jam. Laser is very hard to detect (unless you go faster than speed of light), but legal to jam.
    - hunter2_ 2y ago
      The laser shifters are plainly visible on the grill near the intercooler/radiator, while the radar receiver is behind a solid part of the bumper cover. Radar works great despite the low elevation compared to a high windshield mount. Laser shifters died years ago (bulging like bad capacitors, white crust seeping out). I only have front mounted stuff, although the main controller does have unused ports to add rear stuff, so yes you could say my particular setup is non-360. I don't really mind losing the laser shifters. Jam detection is a ubiquitous feature of police units as I understand it, and I'd rather not poke that bear even if it's totally legal. The technique, though, is to cancel the jamming after just a few seconds during which you reduce your speed, such that ultimately you allow a good reading to overcome any suspicion of jamming. Some people like to automate the delayed cancellation, while others prefer to manually cancel. Interesting, but not for me.
JohnMakin 2y ago
People saying this tech is just for speeding are wrong. I have a high end model that's legal in california (radar detection is legal, although cops will hassle you and say it isn't - any unit with a jammer installed is illegal whether you're using the jamming or not. They don't really seem to know the difference, so beware). I drive reasonable speeds but have a loud car that will get pulled over for "noise" (it's unmodified and legal) which are usually just fishing expeditions. Since police cruisers in my state usually emit radar signals constantly, the detector basically gives me a heads up when a cop is within ~ 0.5 miles of me, which I find useful whether I am speeding or not. Limiting my interactions with police is a worthy goal, since police can be dangerous and unpredictable and shoot-y.
- anonymousiam 2y ago
  I'm curious about what car you drive. My previous car was 100% stock, but would wake up the whole neighborhood on cold mornings. I never got pulled over for noise, but I did purchase my first V1 for it after being cited in a speed trap just two months after I bought the car.
  - JohnMakin 2y ago
    A dodge hellcat. It is loud, but it is legal.
Karunamon 2y ago
Its strange to see so much moralizing in this thread about a device which only receives signals and can't harm another being unless maybe thrown hard enough. Most speed limits are artificially low to the point where slavish adherence makes them the safety issue, rather than everyone else breaking the law.
anonymousiam 2y ago
Just two days ago, I applied the "V1 Gen2 Better-Still UPGRADE: Early-September 2024" to my device. I've been a customer for 15 years, and this is my second V1. It's an amazing device, and an essential defense against speed traps. I hope that the company can continue without Michael, but I fear that it was a one-man show. R.I.P. Michael.
legitster 2y ago
Valentine's products basically came onto the market at the same time as radar guns. He was right there at the cutting edge reverse engineering new technology. And regardless of how you feel about the legality now, "speeding" was also a new concept at the time. There was no consistent federal speed limit rules. There were rules about pedestrian safety and reckless driving, and there were periods of gas conservation rules during WWII. But there was not a strong moral basis to stay under a certain speed on a motorway. Valentine was in every way a hacker. The radar detector is right up there with the Wifi Pineapple and Flipper Zero.

    Around here, the problem isn't the people going faster than the speed limit. The problem is the driver who absolutely must go 10, 15 or 20mph than the other cars. The weaving and dodging is so dangerous. It's one thing to risk your own life. These people are risking everyone else's by zipping around them.
    - hmmm-i-wonder 2y ago
      Anyone 10+ mph outside the flow of traffic in either direction, combined with overly aggressive or overly cautious moves (i.e. unpredictable compared to other drivers) are dangerous. Unfortunately you can't convince half this group they are part of the issue and the other half doesn't care.
      - bradlys 2y ago
        What I worry is the skill of drivers who think going 10mph faster than the flow of traffic is dangerous. You pitch 10mph speed difference as if Louis Hamilton is out on the road flipping cars left and right.

I wonder how many premature deaths and life-altering injuries were enabled by people using his devices to get away with endangering other people.

I've seen more near accidents from people braking hard after seeing a cop.

Same question but about guns.
techjamie 2y ago
The US government did a study on highway safety impacts from radar detectors in 1988[1]. While they were able to determine that the presence of a radar detector increased aberrant braking, none of that aberrant braking caused a collision or seemed to be inherently unsafe to other drivers, and also the amount it was observed was statistically very low. They weren't able to determine what the effect was on if a radar detector resulted in more speeding because that was too complex to study though.

I remember the ads in old Car&Track and Road&Driver magazines at the doctor’s office. They always had a veneer of illegality to them, even in states where they were legal. Funny how something like Waze doesn’t. I wonder if it’s that Waze is just the technological equivalent to the oncoming driver flashing their brights at you.

I remember thinking the same thing as a kid reading C&D magazines at the doctor's office. I think they showed up in PopSci a few times too. "wait, this is allowed? Cool!"
neilv 2y ago
There was also at least one recurring ad for a purported radar jammer. Either in the car magazines or the electronics ones. It might've been "sold in legal kit form".

The primary reason most people own radar detectors is for bullshit speed limits and speed traps. Very few are people looking to street race or be reckless drivers.

JSR_FDED 2y ago

I remember my Valentine V1 fondly. It was so clearly and immediately better than all the other radar detectors. Knowing where the signal was coming from was a game changer. I’m not saying speeding is good, but when you’re on the road a lot and are a responsible driver there are definitely places where you can safely exceed the speed limit and where it feels like the police see enforcement as a fundraising opportunity rather than a safety issue.

toomuchtodo 2y ago
I purchased my first one in the early 00s, and while I don't use it anymore, I have kept it because I love the engineering that went into it. I also had the opportunity once to talk to Michael on the phone, but did not know it was him at the time. I was inquiring how to get data off the ext port to correlate with GPS data, before Waze reporting was a thing (I was trying to create a historical speed trap map in my locality). He was knowledgable, but also patient and kind with my unsophisticated questions. A good engineer has left, that's the story, and that is sad.

Police still don't have the radar detector detector.

antonkochubey 2y ago
They do - Spectre Elite is the most common RDD around. However, it only detects low-quality and old radar detectors, newer ones are much harder to pick out since they don't emit noise on their superheterodyne frequency.
- bradleyy 2y ago
  Also, in an ironic twist: Uniden makes the radar detector detectors... and radar detectors which are immune. R7/R8 for the win!
bluGill 2y ago
Most places radar detectors are legal. Several courts have even said that the purpose of radar is to slow people down and so radar detectors work just as well as traffic tickets (this was years ago - I'm not sure what the latest case law is) and so you can't make them illegal. The FCC also generally says receivers are legal (again I haven't checked in 25 years so I'm not sure what the latest is). Radar detector detectors exist and are used in places where radar detectors are illegal. As others have pointed out they are limit used against modern radar detectors.

> The automotive industry has lost one of the great saviors of speed. The article glamorizes speeding. Here's one reason not to: Imagine a speeder hitting someone, and the difference between the innocent person being OK, and being disabled/killed, was the speeding. That's not hard to imagine, and seems to be a frequent occurrence in the US. Another thing to imagine: Imagine that everyone obeyed speed laws. Wouldn't there then be more pressure to make the laws more sensible? Instead, we have dangerous speeding by random people, who feel justified in it, and a ton of people individually and unilaterally trying to apply their own judgment of what speeding of theirs is safe for others. Personally, I sure don't want the stupidest and cockiest people deciding what's safe for 'themselves', and applying it counter to the expectations of imminent victims. When we normalize speeding, that's what we get.

sokoloff 2y ago
When we normalize 55 mph speed limits on roads where 80 mph is completely reasonable, that’s also what we get: plenty of people breaking a bad law. (If over 95% of people break that law, it’s clearly not codifying what behavior society expects/demands of its members.)
crazydoggers 2y ago
The problem you’re ignoring is that there are many places around the country where speed limits are set unreasonably low with the intention of collecting revenue. Until we seperate speed enforcement from revenue collection, then speed limits won’t be about the science and engineering or what is safest for the road, but what is collects the most revenue. I’ve witnessed firsthand a major roadway whose speed limit was lowered from 65 to 55 arbitrarily, along with a jump in enforcement. The road is definitely less safe in fact, since I’ve noticed people on their phones more as the lower speed gives people more confidence. The people who speed dangerously and no speed limit will stop, now drive more aggressive around cars with greater differentials in speed. One time I drove behind a women who I could clearly see had her phone propped up on her steering wheel. She and others driving irrationally or dangerously but at or below the speed limit drive right by the police. At one point when I was stopped for going 60 and given a warning, I asked how come they don’t stop people driving dangerous or on their phones. He’s response was the “laws didn’t let him”. I’m assuming he really meant they can’t reliably collect fines for it since they can’t prove it in court with a radar detector. > Personally, I sure don't want the stupidest and cockiest people deciding what's safe for 'themselves', and applying it counter to the expectations of imminent victims. When we normalize speeding, that's what we get. The safest is supposed to be 85% percentile of speed on a given roadway. Many places have this specified in the books at a state level, however, after doing some research on that years ago, that’s almost never followed locally.

With many (non-police) cars now having radar for collision avoidance, are radar detectors still useful?

hunter2_ 2y ago
I only happen to know because I bought a slightly used car in which the first owner had an Escort Max Ci professionally installed. Sensor in the bumper cover, display and controls mounted to the dash with hidden hard-wiring, quite nice. There were a ton of false positives from non-police sources at first, especially Cadillacs if I recall correctly. Then I learned how to disable alerts on all the bands except those known to be used in the places I do most of my driving (2 states) based on websites that specialize in such information. I think I reduced it from like 30 slices of the K band down to about 6 or 7. Problem solved! Granted, it introduces the possibility of encountering police who use bands I've disabled, but I prefer that over a bad SNR. Now I see a cop for about 1/4 of the alerts which is pretty nice. Visible line of sight is often not until the alert has been going for sufficient time to acknowledge.
- OptionOfT 2y ago
  I'd go and double check whether the sensors in your bumpers aren't laser jammers. The Escort Max Ci 360 (not sure if there is a non-360 version) has laser jammers, and that is what those modules are in the front and rear bumper. Radar is easy to detect, but illegal to jam. Laser is very hard to detect (unless you go faster than speed of light), but legal to jam.
  - hunter2_ 2y ago
    The laser shifters are plainly visible on the grill near the intercooler/radiator, while the radar receiver is behind a solid part of the bumper cover. Radar works great despite the low elevation compared to a high windshield mount. Laser shifters died years ago (bulging like bad capacitors, white crust seeping out). I only have front mounted stuff, although the main controller does have unused ports to add rear stuff, so yes you could say my particular setup is non-360. I don't really mind losing the laser shifters. Jam detection is a ubiquitous feature of police units as I understand it, and I'd rather not poke that bear even if it's totally legal. The technique, though, is to cancel the jamming after just a few seconds during which you reduce your speed, such that ultimately you allow a good reading to overcome any suspicion of jamming. Some people like to automate the delayed cancellation, while others prefer to manually cancel. Interesting, but not for me.

JohnMakin 2y ago

People saying this tech is just for speeding are wrong. I have a high end model that's legal in california (radar detection is legal, although cops will hassle you and say it isn't - any unit with a jammer installed is illegal whether you're using the jamming or not. They don't really seem to know the difference, so beware). I drive reasonable speeds but have a loud car that will get pulled over for "noise" (it's unmodified and legal) which are usually just fishing expeditions. Since police cruisers in my state usually emit radar signals constantly, the detector basically gives me a heads up when a cop is within ~ 0.5 miles of me, which I find useful whether I am speeding or not. Limiting my interactions with police is a worthy goal, since police can be dangerous and unpredictable and shoot-y.

anonymousiam 2y ago
I'm curious about what car you drive. My previous car was 100% stock, but would wake up the whole neighborhood on cold mornings. I never got pulled over for noise, but I did purchase my first V1 for it after being cited in a speed trap just two months after I bought the car.
- JohnMakin 2y ago
  A dodge hellcat. It is loud, but it is legal.

Karunamon 2y ago

Its strange to see so much moralizing in this thread about a device which only receives signals and can't harm another being unless maybe thrown hard enough. Most speed limits are artificially low to the point where slavish adherence makes them the safety issue, rather than everyone else breaking the law.

anonymousiam 2y ago

Just two days ago, I applied the "V1 Gen2 Better-Still UPGRADE: Early-September 2024" to my device. I've been a customer for 15 years, and this is my second V1. It's an amazing device, and an essential defense against speed traps. I hope that the company can continue without Michael, but I fear that it was a one-man show. R.I.P. Michael.

Valentine's products basically came onto the market at the same time as radar guns. He was right there at the cutting edge reverse engineering new technology. And regardless of how you feel about the legality now, "speeding" was also a new concept at the time. There was no consistent federal speed limit rules. There were rules about pedestrian safety and reckless driving, and there were periods of gas conservation rules during WWII. But there was not a strong moral basis to stay under a certain speed on a motorway. Valentine was in every way a hacker. The radar detector is right up there with the Wifi Pineapple and Flipper Zero.
