Or, just add speed bumps, curves, narrowings in the road, etc, to naturally bring the speed down. Then it works on everyone, whether they have the nanny tech or not, and you avoid the difficult problem of determining the speed limit accurately 100% of the time across every segment of road everywhere.

This is kind of like the (apocryphal) "NASA spent millions on a pen that would work without gravity; russians just used pencil" parable.

While it can be overridden, hopefully this saves many lives. We limit speeds on scooters and e bikes so cars are only fair

Was driving a rental with speed limit indicators and warning beeps this weekend in Germany. Over the course of a couple days, it was maybe 95% correct, but had major issues with what were probably former construction zones on the Autobhan and some limits near towns. There were a few times where it was giving technically correct "national speed limit" answers for .. not fast roads.

On the Autobahn, it wanted me to slow to 80 in a no speed limit zone a few times, when the general flow of traffic was ~ 130 or so. It was increasingly annoying beeping, but had it actually slowed down, it would have been a severe issue.

This is the first time I've been driving a car with lane assist or active speed control, and I'd say that it increased the congnitive load, especially in trickier situations where there were narrow shifting lanes (due to construction). It may have helped in the easy case, but that's the easy case, and I can handle it.

Alerts were definitely distracting, to the point of taking my attention from the road at potentially bad times. I'll also point out that there was a medium screen tilted toward the driver, that had a freaking youtube app on it, and the instrument cluster is basically a video game now. So a couple of alerts are just the tip of the iceberg.

I may be old enough to yell at clouds now, but I really prefered the full analog, numbers only view of the car's instruments. Text is slow.

Leaving aside the concerns about the tech not working well, I'm really not a fan of this pre-crime stuff. This feels very Big Brother, where someone (or some system) is watching over you so you don't break any laws.

Things like this lead to cultural ossification and are a nightmare scenario for me.

This is terrifying. I routinely cross a bridge with a 30ton weight limit, which my car mistakes for a 30km/h speed limit sign. I would cause an average of 2 accidents per month if I suddenly slowed from 70 to 30 and the people behind me weren't paying attention. The technology is _not_ there and this won't save lives, potentially it will cause deaths. (Yes I read the article, this is initially only "for the driver's…

Apparently you didn't. The most proactive method is "a speed control function in which the speed of the vehicle will be gradually reduced", and "the system can be smoothly overridden by the driver by pressing the accelerator pedal a little bit deeper", so your hyperbolic reaction is overwrought.

Is it though? When has government regulation ever decreased?

Give them an inch...

It won't stop reckless driving on roads where the legal limit is way above the practical limit. Although I have absolutely zero stats to backup my argument, I'd say deaths on twisty country roads where the vehicle was under the legal speed limit far exceeds those on straight motorways breaking the limit.

My hope is that it lowers the number of people who do 50km/h on 30km/h residential streets and prevents pedestrian deaths.

You clearly identify the important pieces and then chose to ignore them to arrive at the weirdest of conclusions. I am confused.

This is one example of legislation that mandates fantasy tech that doesn't exist. You'd think that something as simple as speed limiter should be very easy to implement, and it couldn't be further from the truth - watch any review of a car with this tech and every reviewer will complain that it's not the presence of the system that's the problem, it's the fact that it constantly gets the speed limit wrong. Either rea…

Agreed that the general case is hard to solve. I think you could at least make a case for solving a simpler problem. What's the highest legal speed limit in the country in which the car was sold? Set a global speed limit to that.

This could make it impossible or dangerous to pass in many situations where it may be necessary to temporarily exceed the speed limit.
