I’m struggling to understand your point, or to imagine many examples which support it. I agree that brief minor parking infringements may occasionally make people’s lives more efficient; but I can’t think of any examples where traffic lights and speed limits need to be routinely disregarded?

From what I remember of my CA driver’s license test (had to re-take the written test when I moved to CA), there is no actual speed limit in CA. The speed limit is “whatever conditions deem safe”. Maybe OP meant something like that?

  As someone who got their first drivers license in California, I can say with certainty that there are in fact speed limits.

  You might want to review the handbook again. What you’re referring to is the basic speed law, which never trumps the absolute speed limits posted (or the special restrictions like the 15 mph railroad track law). Think of it as a clamped function: the speed limit is min(posted limit, safe speed under current conditions).
- kelnos 2y ago
  No, that's not true (CA driver here too). The "whatever conditions deem safe" bit is something that can reduce the legal speed below the posted speed limit. It can never raise it above the posted limit. Even with no posted speed limit, there is an implicit limit in CA (differs based on the type of road and surrounding locale), and "conditions" can again only reduce that.

It's sometimes safer to speed up 5mph over the limit to get through a yellow light, than to slam your brakes with someone behind you. It's frequently safer to speed to match people speeding around you then to match the stated speed limit (usually on freeways).

  These are both problems caused by poor driving (other peoples' in this case). Maybe with a traffic law panopticon everyone would drive better and these would disappear

    This is actually a problem with speed limits that don't match the road or alternatively, roads that aren't designed to incentivize people driving the intended speed. In theory, the speed limit should be set to the 80th or 85th percentile speed of traffic, and the road should be engineered so that the 80th percentile speed is appropriate to the surroundings. https://www.mikeontraffic.com/85th-percentile-speed-explained/ https://www.mikeontraffic.com/85th-percentile-speed-explaine... https://en.m.wikipedia.org/wiki/Traffic_calming https://en.m.wikipedia.org/wiki/Traffic_calming

      I'm extremely skeptical of this idea of "speed limits which don't match the road" unless people are arguing them down. Because the whole point is that people reliably overestimate their driving ability, and thus overestimate the safe rate of travel on a road. The road I live on displays this all the time, and that's just an advisory road: the speed limit going down the winding slope near my house is about 50 kmh...that is probably the absolute maximum you can navigate those turns at in perfect conditions, and in reality it's considerably slower - and there are steep embankments either side, so if you lose control your car is at the mercy as to whether or not a tree will stop it plunging over the edge. Anyway, there's been a fair number of damaged cars and one near miss from said creek plunge in the 2 years I've lived here.

        You live on an extreme road where road engineering can't do much due to the given environment and possibly low budget if the road is not that important. Though anything that slows vehicles before entering this stretch of road, or a much less harmful obstacle to heighten their awareness could improve the situation. Roads where planners have a literal blank sheet is where roads need to be designed better to slow down drivers to the desired speed limit. Sometimes it's as simple as adding traffic islands for pedestrians, narrowing the road or planing trees next to the road.

It's not just about efficiency, it's also about quality of life. There is a reason that a cop has permission to use his judgement when deciding to write a ticket or not. Because life is better when we don't live under the oppression of draconian rule keepers all the time. Rules are meant to protect people, and as such are often specified in terms of the lowest common denominator, with the understanding that the system doesn't enforce them when they can be reasonably ignored, using good judgement. Life will be shittier for everyone if an army of self-empowered rule-loving busybodies get to expand their current powers beyond the realm of the HOA.

  Frankly I'd rather just get a ticket when I speed by a traffic camera than rely on the discretion of a random police officer who might just be looking for a pretense to search my vehicle or hassle me in some other way.
  - refulgentis 2y ago
    Jaywalking, to my ear, is a similarly universal & easy example for this not being universally desirable.
    - c22 2y ago
      It's probably not universally necessary to jaywalk. However, I am against this on the grounds of logistics. I understand and accept the need to have a license and display an identifier while operating a vehicle, but I think this would be an extreme requirement for people walking around (and possibly unconstitutional in the US?) And without this identifier, how will the system know where to send the citation? All things being equal though this doesn't even sound inherently bad. If every jaywalking infraction was cited we might democratically re-decide how much we want that law to be on the books.
      - kelnos 2y ago
        And indeed, California no longer has strong jaywalking laws on the books. A cop can only cite you for jaywalking if you're crossing dangerously. Crossing on a red light, do-not-walk sign, or at a place where there isn't a crosswalk is no longer automatically considered jaywalking.
repeekad 2y ago
You clearly haven’t received a letter in the mail for $250 because a camera saw you barely not fully stop for a red light right turn at 3am with zero traffic A human in the loop needs to be the first line of defense, if an officer isn’t willing to be in the field to issue the ticket and show up in court to defend it then there shouldn’t be a ticket in the first place, full stop
- askvictor 2y ago
  Were you in that much of a hurry to not be able to wait 30 seconds for the traffic light?
  - repeekad 2y ago
    That’s not the point, a surveillance state where the panopticon autonomously gives $250 tickets is the issue Rules aren’t meant to be cold hard algorithms to blindly punish people with; we wouldn’t automate a judge with an algorithm why is it somehow different to automate a police officer with one?
    - froggit 2y ago
      > Rules aren’t meant to be cold hard algorithms to blindly punish people with; we wouldn’t automate a judge with an algorithm why is it somehow different to automate a police officer with one? The role of enforcing certain laws can be easily fulfilled with simple algorithms as the logic required is on early grade school level. In this case it's something like: if "stoplight is red" and "car doesn't stop", then "driver gets ticket." That's all the algorithm has to do, super easy to automate. Automation allows for enforcement where it would otherwise not be cost effective, like when it's 3am and no one else is around. The judiciary, however, has to interpret all kinds of crazy edge cases that people come up with to try and get out of tickets for rolling stops or whatever legal case, for all laws, because every now and then someone has a valid case. That's a bit harder to do with a couple lines of code and some low cost hardware.
    - try_the_bass 2y ago
      Why is that not the point? You violated a law and received a penalty. You're not disputing that you violated said law, but are instead trying to justify it with "barely didn't stop" and "it's 3am and there is no traffic". Isn't the point that you got punished for doing something you would have gotten away with had no one been watching?

I was just discussing this with my wife while driving on the local expressway on a clear Saturday afternoon. The speed limit is 55 MPH but everyone was moving at 70 MPH without any issues. The road is wide and straight with limited on/off ramps and the faster speed felt very natural. This is a common occurrence on this road and everyone seems to abide pretty well. Sure, there is the occasional "idiot" doing stupid things (weaving in out of traffic, speeding up / slowing down, etc.) but for the most part it just works. The big problem is when a LEO is around. Everyone slows down to 55ish MPH and traffic backs up and people do weird things. However, I don't know the solution. If we raise the speed limit to 70 MPH does that mean that people will then feel comfortable going 80 or 90 MPH? If we lower the speed limit to 30 MPH will that cause everyone to only go 55 MPH? This piece of road just feels right and natural at 70 MPH; everyone seems to think so, if unconsciously. Will changing the laws "fix" this piece of road?
- kelnos 2y ago
  The problem with speed limits in general is that they're not universally applicable. Darkness, fog, rain, snow, etc. can all change what the actual safe maximum speed is. So even with a posted 55mph speed limit, the maximum safe speed at a particular time might be lower (even considerably lower), and a LEO could cite you for going too fast even if you're driving under the posted limit. (I've been on the interstate in the snow where you'd be likely to get pulled over if you were going much over 25mph, even with a posted 65mph limit.) Driver skill and reaction time also plays a factor, but of course people are not so great at judging what their own specific safe speed is all the time. And all other things being equal, you're more likely to get into a crash if you're driving faster rather than slower, and the injuries you sustain will be worse at a higher speed. IIRC speed limits are often set at some percentile (85th?) of what all drivers would (theoretically) "naturally" drive if there was no posted limit. And, on highways, cops will often not pull people over for exceeding the speed limit by a moderate amount. Once, long ago, a cop told me that, absent adverse conditions or other unsafe behavior, he usually will not stop anyone unless they're going more than 10mph over the highway speed limit. And I expect if he were hiding in a speed trap that no one could actually see driving by, and everyone was going 70mph on your 55mph road, he'd probably just sit there and not bother anyone, unless they were doing something else that was unsafe. I guess this is a long winded way to say that there really is no single safe speed that applies to everyone, in every road condition. The law acknowledges this, and police often let you do your thing unless they believe you're actually doing something unsafe. The discretion and judgment calls can be a problem (biases, etc.), but I don't think a society where unavoidably "fuzzy" laws were always prosecuted would be a great society either.

Properly set speed limits would not need to be routinely disregarded. We don’t have those right now (IMO).
