This unwritten distinction exists only to allow targeted enforcement in service of harassment and oppression. There is no upside (even if getting away with speeding feels good). We should strive to enforce all laws 100% of the time as that is the only fair option.

If a law being enforced 100% of the time causes problems then rethink the law (i.e. raise the speed limit, or design the road slower).

Isn't this the point of the whole conversation we are having here?

Laws on copyright were not created for current AI usage on open source project replication.

They need to change, because if they are perfectly enforced by the letter, they result in actions that are clearly against the intent of the law itself.

The underlying problem is that the world changes too fast for the laws so be fair immediately

What would really help is for people to understand that that's the "spirit of the law" and the "letter of the law".

People don't want the letter of the law enforced, they want the spirit. Using the example from above, speed limits were made for safety. They were set at a time and surprise, cars got safer. So people feel safer driving faster. They're breaking the letter of the law but not the spirit.

I actually like to use law as an example of the limitations of natural languages. Because legalese is an attempt to formalize natural language, yet everyone seems to understand how hard it is to write good rules and how easy it is to find loopholes. But those are only possible if you enforce the letter of the law. Loopholes still exist but are much harder to circumvent with the spirit of the law. But it's also more ambiguous, so not without faults. You have to use some balance.

>cars have gotten safer

For their inhabitants, maybe not pedestrians though. Speeding laws are in part for protecting pedestrians

In general cars have also gotten safer for pedestrians[0]. Modern cars are lighter and made of plastic. There's better visibility, sensors, and for most vehicles the shape of the car has improved things.

American trucks are an interesting counter example but that's a more complicated issue. (The source has a comment that you can infer this being a concern with trucks but there's also a lot of sources on this that you can easily find)

^This. A large % of jurisprudence is in just trying to keep up with how tech disrupts society.
The reason that has to be done is precisely that the law has no common, well-architected rationale. The vast majority of law in common-law jurisdictions is ad hoc precedent from decades or centuries ago, patchwork laws that match current, ephemeral intuition about what the law should be, etc. Perfect and inevitable enforcement makes this situation a nightmare, given the expectation that the average US citizen commits multiple felonies per day. Something will have to give.
The speed limit example is a great one. Consider a road that has a 35mph limit. Now - which of the following scenarios is SAFER: a) I'm driving on the road in a brand new 4x4 porsche on a sunny day with great visibility and brand new tyres. Doing 40mph. b) I'm driving on the same road in a 70s car with legal but somewhat worn out tyres, in the dark, while it's raining heavily. Doing 35mph.

Of course technically option a is violating the law but no sane police officer will give you a fine in this case. Nor should they! A robot will, however. This is stupid.

The Cayenne would be safer going 35 instead of 40 regardless of all other variables. It's a trivial physics question, kinetic energy is a function of mass and velocity.
The Cayenne would not be safer going 35 instead of 40 "regardless of all other variables": it's statistically safer to go closer to the flow of traffic because you're then "at rest" with respect to other drivers (assuming a controlled access road without pedestrian traffic). If the speed limit is 55 and the flow of traffic is 70–80 (as is the case with the Beltway around DC, despite automated enforcement), then going 55 is more dangerous than "speeding". The issue with 100% enforcement is every law assumes certain circumstances or variables and the real world is infinitely more complex than any set of variables that can reasonably be foreseen by law (and laws that attempt to foresee as many variables as possible are more complicated and, consequently, harder for normal people to apply, which is another reason for latitude in enforcement).
safer for whom? Remember cars are not the only ones participating in traffic.
“assuming a controlled access road without pedestrian traffic”
such roads barely need speed limits. In some places they do not have them
The problem with your DC beltway example wouldn’t be automated enforcement then, but with the speed limit itself.

A road without pedestrians and intersections in it should have a speed limit that reflects the reality of its use (70-80)

I meant a 911 but thank you for answering a completely different point than what I was making.
The reason we have speed limits isnt due to vehciles being unable to 'handle' certain speeds though, it's to minimise the damage of an incident at that speed, which is entirely a matter of physics.
No, that is not true. I used to work on road signage systems, where we would use test vehicles, sensors, and math to figure out what the correct signage should be for various sections of road. The standards are primarily concerned with maintain a margin of error for the "worst" cars on the road, i.e. the ones that meet only the minimum inspection requirements. What happens once that margin of error is exceeded was anyone's guess, but practically could be wildly different for specific scenarios that had more to do with the off-road environment than the exact parameters of the road. Two roads with identical bends would receive the same signage regardless of whether under steering through the curve would land you on a sidewalk or in a field or over a cliff.
AFAICT at least 2 people in this thread don't seem to think that visibility -- a function of, among other things, weather and time of day -- influences driving safety. I find this amazing.

The point of terryf's example was to point out that for practical reasons, existing laws don't capture every relevant variable. I (but not everyone, it seems) think that visibility obviously influences safety. The point I want to make is that in practice the "precision gap" can't be perfectly rectified by making legality a function of more factors than just speed. There will always be some additional factor that influences the probability of a crash by some small amount -- and some of the largest factors, like individual driving ability, would be objected to on other grounds.

"Regardless of all other variables"

Variable 1: The Cayenne is on a train track

Variable 2: The train behind the Cayenne is going 35mph.

You painted with too broad of a brush with that statement.

If there was an accident an officer might give you a fine in both cases where I live. In the Porsche case they can say you broke the law and were speeding that led to the accident. But also in the case of old car for failing to adjust your speed to your skills, the state of your vehicle and conditions of the road and weather regardless of the speed limit.
The classic. In Bulgaria they used to do that (and maybe still do). Every time there was an accident they'd often write up everyone for "speed not matching the conditions" with the idea that all accidents are avoidable, you just weren't going fast/slow enough so git gud and don't forget to pay in the next 2 weeks to get a discount.
Yes! This is exactly the point - machinistic enforcement makes no sense in case of speed limits. All laws about driving explicitly say that at the end of the day it's the driver's responsibility to drive safely and if they cause an accident, then they are at fault in some cases even if they followed the speed limit.

The point is that whether you drove dangerously is not a strict, machinistic "if-then" assessment. Automatic enforcement of speeding is ridiculous when viewed in this context.

And the people saying "yes but there is more energy in a faster vehicle" have clearly not felt the difference between driving a car with drum brakes vs modern brakes.

A system that solves for absolute compliance in every individual case does not result in the emergence of a fairer society.

There are numerous cases, both in history and in fiction, that demonstrate as much.

exactly what it ends up with is a surveillance state. Looking at you China.
What, do you expect techbros to have media literacy? We wouldn’t be in any of this mess if they did.
If speed limits were automated rigidly enforced 100% of the time, it would be impossible to drive.

>only to allow targeted enforcement in service of harassment and oppression

That's absurd hyperbole. A competent policeman will recognise the difference between me driving 90 km/h on a 80 km/h road because I didn't notice the sign. And me driving 120 km/h out of complete disregard for human life. Should I get a fine for driving 90? Yea, probably. Is it a first time offence? Was anyone else on the road? Did the sign get knocked down? Is it day or night? Have I done this 15 times before? Is my wife in labour in the passenger seat? None of those are excuses, but could be grounds for a warning instead.

> If speed limits were automated rigidly enforced 100% of the time, it would be impossible to drive.

Why? Plenty of people drive in areas with speed cameras, isn't that exactly how they work?

> That's absurd hyperbole. A competent policeman will recognise the difference between me driving 90 km/h on a 80 km/h road because I didn't notice the sign.

I'm not sure it is hyperbole or that we should assume competence/good faith. Multiple studies have shown that traffic laws, specifically, are enforced in an inconsistent matter that best correlates with the driver's race.

If you find it impossible to follow a simple speed limit, then getting you off the road is the ideal outcome.

Please shred your drivers license immediately, if you at any point in your life have exceeded the speed limit by any amount, or otherwise violated the traffic regulations in any way whatsoever.
Why? 1) If grandparent commenter got a moving violation, shouldn't they just face the corresponding - why posit a made-up penalty for the violation? 2) And if people know there is perfect enforcement, wouldn't they be expected to adjust their behavior going forward, such as driving enough below the limit that they won't accidentally exceed it?
>driving enough below the limit that they won't accidentally exceed it

That is precisely why traffic would effectively grind to a halt. Because going even 0,0001 over the limit is so easy, you would have to turtle through traffic to get anywhere while making certain you never go above the limit. 50km zone is now 30km, and you didn't decelerate quickly enough and were going 32km at the threshold. 60km zone, but you accelerated too quickly and hit 61km for a moment. And sometimes, rarely, but sometimes you have to accelerate yourself out of a dangerous situation.

Honestly if you are arguing for this idea, I strongly suspect you have no experience driving. I've driven for about 25 years. I've received two speeding tickets. One in Germany (I'm danish), where I got confused due to unfamiliar signage and got dinged for going 112km in a 100km zone. And once here I got a ticket for going 54 in a 50 - my mom was at the hospital, possibly about to die (she didn't). Both of those were speed traps.

How close to your desired speed are you able to maintain?

> 50km zone is now 30km, and you didn't decelerate quickly enough and were going 32km at the threshold.

Is the argument that you and others would be unable to safely achieve the posted speed within the speed limited area? For example, if you feel you can't drive more precisely than 40-50 when you are aiming for 45, in the above scenario, you could start with your goal being 45, then in the 30 zone aim for 25, knowing that you'd be going no faster than 30 when your intend to drive 25.

> 60km zone, but you accelerated too quickly and hit 61km for a moment.

Should you aim for 55, if for example the most precise you can do is +/- 5? Or adjust correspondingly for how precise you are able to keep within a desired range.

And of course:

* In a world where enforcement was more consistent, we might expect speed limits to eventually be adjusted - i.e. are speed limits currently set lower than what is technically safe because we assume that some portion of people will currently break the law?

* With self-driving, or at least automated speed-keeping (but not steering) there will no longer be the issue of someone having the problem of being unable to stay within x km/h of the speed they're targeting.

Everybody going 30km/h does not constitute “halt”
That is completely different argument. Yes, I exceeded speed limit here and there. I am not deluded enough to think it was "unavoidable" or "impossible to drive slower".

It is perfectly possible to drive and obey all speed limits. It is even technically easy. Us people choosing not to do so, because we are impatient, feeling competitive against other drivers or because we just think we can get away with it now does not make it impossible.

Laws can't be enforced 100% of the time because many laws require intent, which is unknowable. You have to make an educated guess behind it. Even if someone tells you their intent, straight up, you still don't know their intent. You just know what they want you to think their intent is, which may or may not be the same thing. It's legitimately unknowable.

Ideally, for a lot of things we want to punish people who knowingly do bad stuff, not people who do bad stuff because they thought it was good.

Very true but not in all cases. In case of speed limit intent does not matter; "I didn't know I was speeding" is no excuse. Same with DUI.

In fact DUI should be a mitigating circumstance, because when you're drunk your ability to make decisions is impaired -- but the opposite happens, DUI is an aggravating circumstance.

What about drunk driving laws?
Same argument applies. Driving slowly for 1km 0.01 under the speed limit, over legal blood alco limit is safer than driving at the speed limit for 10kms just under the alco limit.

It's very easy to come up with thought experiments to show that technically illegal scenarios are not necessarily more dangerous than some legal scenarios.

The law is often made to be easy to apply, not for precision. Hard to see how anyone could see otherwise.

That's not say that the laws are necessarily problematic. You have to draw the line somewhere.

There is an upside: oppressing people who consistently engage in antisocial behavior is good and necessary.
The whole point is that only some of those engaging in anti-social behaviour recieve punishment.
Right. People who only intermittently engage in such behaviors should be treated differently than people who consistently engage in them.
