  Seems incredibly dangerous. Imagine some bad GPS reading warps you from a highway to a school dropoff zone and decelerates you to 20mph
  - galdosdi 4y ago
    Minus the word "incredibly" which is quite an exaggeration, I agree. But, it can be made pretty safe. Entirely safe in fact, for good drivers (less so for shoddy ones) The fine details of implementation are not noted so we can only speculate. I would hope it's designed to very gradually start limiting the speed after X seconds of alerting the driver. That said, even the most naive design, which would work the same as RPM limiters (which all cars have to avoid engine damage) would just cut fuel injection whenever over the limit. This produces about the same effect as coasting in neutral, so even then you are going to coast to a stop very very gradually and have lots of time to make it to a shoulder. That said, even that does present some danger -- not to me or you of course, but you know, to shitty drivers who might not be accustomed to driving cars that fail at random and might panic and fail to cope appropriately with the situation. I mean, I have even ridden with drivers who are afraid to stop on the shoulder, even in a situation that warranted it, so it's bound to happen now and then. A manual override if available, will help here, but the pool of drivers dumb enough to still be startled into making a mistake will merely shrink then, not disappear.

      I actually wouldn't mind a thing like this that I can manually enable, I am constantly afraid of accidentally speeding and always have my satnav on so it shows the max speed (here in the UK we get penalty points, not just fines, and enough of them can mean you have a temp ban from driving). Don't really like the idea of this being automatically triggered and enforced though.
      - efaref 4y ago
        Automatic triggering seems like a recipe for disaster. My car has a version of this that shows the current speed limit on the display. It is frequently wrong. A road near me shows up as 20mph despite being 30 or 40 in different parts. Other times it sees signs for access roads or side roads and misinterpret them as for the current road (sometimes saying 20mph in a 60mph zone). It's a nice idea, but the tech really isn't there yet. I guess a few high profile incidents and they'll be forced to fix it.
        galdosdi 4y ago
        Yeah, you couldn't possibly roll out automatic triggering without also creating laws to uniformize how speed limits are set and data shared about them across the US (I don't refer to taking away agency from the many local jurisdictions that can affect speed limits for the bajillions of stretches of roadway in the country-- just standardizing requirements so that when some tiny little town adjusts the speed limit frfom 25 to 20 on a 2 block stretch of main street, except after 6PM monday to friday, there is a standard way for them to notify a national DOT database electronically and they are required to do that prior to enforcement) That alone probably makes it a nonstarter in the USA, right?

        > enough of them can mean you have a temp ban from driving And it's not a lot. Being caught a bit over 3 times will lose you a licence, or 2 if you're a new driver. Sometimes you can get an awareness course and get a "pass" on the first time but I think only once every few years. Exceed the limit by too much and you don't get that option and you also get more points. You also will find insurance punishingly expensive for years afterwards.
  - Hanschri 4y ago
    I find it hard to believe that the car would base that solely on GPS readings, it will likely be a combination of multiple systems, including cameras which read signage as you pass it, which is already commonplace in many newer models.
    - steveBK123 4y ago
      Then you’ve never driven a Tesla :-) On autopilot they do periodically do absolutely insane stuff like this due to bad map data, gps drift, lack of recent speed sign reading etc And they are supposed to be best in class
      - johnisgood 4y ago
        ...and people think roads are perfect, too. That is a huge mistake. Try smaller cities in Eastern Europe. There is no way such a car could help you much there. When it comes to self-driving cars, yeah... no. It is really risky.
- vvillena 4y ago
  Nothing more can be done until extensive and affordable level 3 autonomy comes around. This intelligent speed control is just a level 2 assistance feature that needs constant driver monitoring.
yadaeno 4y ago
This is great, data shows that beeping is effective for increasing seatbelts usage, I see no reason why this wouldn't apply to speeding. I hope they take this a step further. Cars should not be able to exceed 90mph unless you have a special license for the track. 99.9% of drivers are not tracking their car and theres absolutely no reason a 6000lb pick up truck needs to go 150mph under any circumstance. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3217543/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3217543/
- BitwiseFool 4y ago
  Unlike the seatbelt chime which is easy to address, speeding beeps would be maddening. Everybody speeds at some point while driving somewhere. Not all speeding is reckless. As far as making someone get a special track license, that just seems like overkill.
  - yadaeno 4y ago
    "Speeding was a factor in 29% of all traffic fatalities in 2020, killing 11,258, or an average of over 30 people per day." Im not saying beeping will stop all of this but I think its a large low hanging fruit in terms of road safety. You will strongly disagree with this but mandatory breathalyzers are another. I would love if these rules were not necessary but drivers (in the US at least) have proven that they are not responsible in aggregate. I dont think anyone disagrees with speed limits, I dont understand the moral panic that comes from taking it a step further and building it into the car. Youre right about needing to speed sometimes though, maybe they need to add a 15% buffer or some kind of "10/10 data points in the last 5 mins required" condition. https://injuryfacts.nsc.org/motor-vehicle/motor-vehicle-safety-issues/speeding/ https://injuryfacts.nsc.org/motor-vehicle/motor-vehicle-safe...
    - johnisgood 4y ago
      He just told you though. Speeding happens, and there are many scenarios in which it is OK. Hearing the beeping might actually induce road rage... or not... I wonder though.

> ISA detects speed limits on roads through devices such as cameras and satnavs. My car will regularly detect speed signs that are adjacent to the highway, including those next to interchanges and exists. On many other occasion the camera detects signs from parallel roads and railroads, where the sign sits simply on the other side of a chain fence. Naturally as a human driver I know that 170km/h doesn't exist on roads, or that a 30km/h isn't a legal speed for highway (except if there is road maintenance or accidents, which has their own contextual clues), but the computer don't know that. Trying to make computers understand context is the running theme of most failures in self driving cars. The only way I could see a speed limiter like this would work is if there were a central control system with local knowledge of the road and those on the road, similar to how a subway control, airport control or rail way control works. cameras and satnavs is only good as an advising tool for an human operative.

  > The only way I could see a speed limiter like this would work is if there were a central control system with local knowledge of the road and those on the road, similar to how a subway control, airport control or rail way control works. Now you're getting, it's all about the control. Once they've got the device in what's to stop the government from saying your car can go 0 miles an hour if they decide it is necessary? It's all about control my friend, all about control.

  I had exactly this kind of problems on an Audi I was renting in Switzerland where the car started suddenly braking while going 110 on a motorway. Freaked the shit out of me and the cars behind me as well. Wtf
- novok 4y ago
  IMO your 170km/h example is a sanity limit you could put into most computer programs. Similarly with GPS assisted general limits and monitoring. (Ex: your in belgium, and the national max speed limit is XXXkm/h, etc)

Tangentially related, if I really want to (and occasionally, i do!), i can disable ABS by pulling the right fuse...

  Cameras and satellite antennas can also be blocked with many common materials

Maybe one of the goals is to make driving so tedious that people happily adopt autonomous features. If someone puts up a fake speed limit sign and tricks your self-driving car to travel 30 mph under the actual limit, then you might not care, if you're having a snooze on a nice reclining seat. Still, I think it's not too early for governments to pass harsh laws against interfering with or obscuring road signs. With some clever networking and an open dataset, it might be possible for cars to detect such missing or altered signs within minutes of the crime being committed.

  >>>> Maybe one of the goals is to make driving so tedious that people happily adopt autonomous features. This has already been achieved in the US without any regulation at all, simply by increasing the amount of traffic on most roads. Maybe it's just that I'm getting old, but driving has gotten to be such a chore that I'm happy to let everything be automated. I've already switched to automatic transmission, lane assist, and adaptive cruise control.
Youden 4y ago
I think the title is a bit misleading. The mandate is for intelligent speed assistance. I own a car with such a feature and I think it's already pretty common in higher-end vehicles even without the mandate. The form it takes in my car is that there's a little symbol with the current speed limit displayed on the HUD. The speed limit is sourced from road signs or the car's navigation data. When you exceed the speed limit, the symbol turns red. Unless you engage "cruise control", that's it. If you do engage "cruise control", a few things happen. First, when the speed limit changes, the targeted cruise control speed will change and the car will either gently accelerate or gently decelerate (think 1kph of change in speed every second or so). You can always choose to override this by using the pedals, changing the set speed manually or turning it off. Another thing the car will do is use radar to maintain distance between you and the car in front of you (the distance is somewhat configurable), which will also mean maintaining speed and coming to a stop if the car in front of you does. However if you never turn on "cruise control", the feature is nothing but an easy to ignore red symbol on your HUD. I really like the feature. Combined with other features like lane keeping assist, it makes driving on the motorway quite relaxing (though you still need to pay attention, this isn't meant to allow you to fall asleep at the wheel or anything).
- buscoquadnary 4y ago
  > or by the accelerator pedal gently pushing their foot back. > In some versions, the vehicle’s speed is automatically reduced. Sounds to me like it isn't so optional, and of course how hard would it be to move it from optional to non-optional?
  - johnisgood 4y ago
    As I understand, you just have to have "cruise control" turned off, and these things will not happen.
  - Youden 4y ago
    The implementation is up to the manufacturer. In my car it's just a red symbol on the HUD. As far as I'm aware the law doesn't mandate the snippets you've quoted.
someweirdperson 4y ago
If it stops beeping you've slowed down too much. Very convenient.
zeeZ 4y ago
My car has a speed limit detection system using a camera and a button I can press to change the speed limiter to the current detected value. It works most of the time, but where it doesn't, it would be a major pain if it was automatic or audible. My onramp to the Autobahn is limited to 80km/h due to a construction zone with the same limit on the Autobahn itself that ends just before the merge. The limit on the Autobahn is ended with a sign, but the one on my onramp is not. Technically I would have to keep driving 80 until I reach my exit, because that was the last posted limit and there are no other signs to change that. Since there are no signs, my car keeps showing me the 80 limit all the way. Realistically I can see the canceled limit sign across the bit of grass and divider at the end of the constructio,n and drive whatever speed seems appropriate in this unrestricted stretch. If the system was audible, would it beep at me the entire way? If it was automatic and try to limit me to 80, I'd cause a major traffic jam, because I'd be constantly passed by every single truck, blocking both of the available lanes. Their speedometers are better calibrated than mine, and I'd be going 77 while they keep at 89.
padjo 4y ago
Would want to be more accurate than than the current tech. Mine regularly gets confused near motorway off ramps and drops speed from 120 to 50. Implementing a max speed of 120 would be good though. It’s never legal to exceed that so why does the car allow it?
- AllegedAlec 4y ago
  > It’s never legal to exceed that so why does the car allow it? Smoothbrain take. It is. If I'm driving on the highway and a dam broke behind me and a 5 meter tall wall of water is coming at me at 180, I am allowed to speed to stay ahead.
aspyct 4y ago
I have a car with an intelligent speed limiter. It is dangerous. I tried it yesterday for the first - and last - time. On the highway, it picked up a speed limit sign that was intended for the side lane, and started reducing my speed fast and unexpectedly. I love the speed limiter, the dumb version. I think it's a super nice way to avoid accidentally going over the speed limit without having to keep an eye on the speedometer, and therefore off the road. I would love to use an intelligent speed limiter. But let's face it, there are always cases where those things will fail unexpectedly and dangerously. That's not even considering voluntary tampering with the road signs. What if I put up a 5km/h sign along the highway. How would the car determine it's bogus? I wouldn't mind a global limiter that prevents going to unsafe speeds well over the highway speed limits.
- midasz 4y ago
  Are there so many unmapped roads in the US? Or are there arbitrary variants of limits? I use Waze in NL and so far, for every road it knows the limit.
  - aspyct 4y ago
    What makes you think I'm in the US? I'm in Belgium, and around here we have a lot of poorly organized road works.
- Akronymus 4y ago
  I have two kinds of speed limiters on my car. One for only allowing up to x km/h unless i fully press the gas pedal in. And one for automatically going y km/h while keeping a certain distance, which can be overwritten by any amount of pressing the gas pedal, or cancelled by any amount of pressing the brake pedal.
  - aspyct 4y ago
    Are you referring to the adaptive cruise control? Sadly I don't have that one, I would love it. However it's not reading the road signs, as far as I know.

I hate these things. My father bought a new car with this nonsense and it's awful and refuses to turn off. See a 130 sign for the train next to the road? Haha, we're going to break really hard down to 30 now. Literally no sign at all anywhere on a 120 road? Haha, we're going 60 now. It doesn't even do it gently. It's terrible. It's an Audi Etron something if anyone is wondering.

I hate these things. My father bought a new car with this nonsense and it's awful and refuses to turn off. See a 130 sign for the train next to the road? Haha, we're going to break really hard down to 30 now. Literally no sign at all anywhere on a 120 road? Haha, we're going 60 now. It doesn't even do it gently. It's terrible. It's an Audi Etron something if anyone is wondering.
