the problem is that the car will limit your speed. it will not just alert you.

this is incredibly dangerous as sometimes you need to drive over the speed limit to avoid accidents or dangerous drivers.

instead of introducing this they should send drivers to driving school and make the police check driver licenses more often and arrest those driving without a license.

in germany you can drive at any speed you want in certain areas of the autobahn and that’s great and actually important to be able to get where you want efficiently. i doubt there are more accidents there. but people actually know how to drive and that is the difference.

these kind of speed limiters are just introduced by politicians to gain votes, it’s easy to sell the population on an idea to punish those driving too fast. easier than to do the right thing, which is to remove idiots who can’t drive from traffic.

This contradicts what the poster above you is saying. Do you have a car that behaves differently and doesn't let you override it, or are you making assumptions?

read the article

The regulators permit something akin to kickdown. While the cars will limit you under gentle/steady state driving, if you floor the accelerator to avoid an accident, the limiters will disengage:

3.6.1.4. It shall be possible for the driver to override the SCF intervention by performing a positive action, for example by pressing the accelerator control harder or deeper.

from https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=OJ:...

at the cost of a delay which could make the difference between life and death

The system acts slowly and and is only active if the driver has engaged it (like cruise control).

You'll be driving at 120kph and you'll notice the car has slowed to 118kph because it thinks the speed limit is 100kph. You push the accelerator and update the speed limit. Done.

I honestly can't see this causing an accident. The thing isn't performing an emergency stop or anything.

I have never really liked that in the USA, the posted speed limit is both the normal speed of travel and the maximum speed permitted. I think legally there should be some allowance for exceeding the speed limit when passing. We have some sections where one must move into the opposing traffic lane to pass, and you have to go over the posted limit to do this. I wonder how the self driving AI software accounts for this.

> I think legally there should be some allowance for exceeding the speed limit when passing

There is. Or rather, there might be. In the US, some states allow you speed while passing. The qualifications on how much you can speed range from "reasonable margin of safety" to specific numbers. And, some states further limit the situations where you can do this, for instance to only allowing it on two lane roads where you're pulling into the oncoming lane to pass.

Mississippi allows for 5 mph at the discretion of the officer. But they generally don't seem to bother in my area unless you're going 15-20 mph over or more.

The car doesn't limit your speed. It only alerts you or updates cruise control. You can always override it by using the pedals. Under no circumstances will the assistance system disable the brakes or accelerator.
