Non issue. This is just haptic feedback when you get to the limit. I hope it does log the speed as well as the last two accidents on the road I live on people were killed by idiots doing 40+ mph in a 20mph limit. What is a problem is fixing this shit when it breaks. Which it will because it adds to the bottom line cost of the vehicle so will be done by the lowest bidder.

If it is just haptic it's OK but the talk was at least in media that it would be an actual speed limit which in current implementation is idiotic. We have a new car which can read speed signs. In theory good idea. But tech isn't where it should be. For example when you drive on highway 100 km/h with 130 km/h speed limit and the car is warning you that you are speeding because it saw speed sign for 40 km/h on exit ramp it's a little worrying if car would actually obey speed limit. Breaking from 100 to 40 for no reason by car itself would not be good. And there are also speed signs for only some vehicles which I don't think any car can read and for example Austrian signs (30 km/h limit and then subtext "valid only for side roads"). And another thing speed signs says limit is 50 km/h. It is valid up to next intersection. Intersection that invalidates speed limit is defined as intersection with more then 4 housing units. It's sometimes hard for human to know if intersection invalidates speed limit or not. How would a car know?

Some vehicles already log the speed -- it's routine in road traffic collisions to read it out of the vehicle computers. As I understand, it only covers the last few minutes prior to engine stop / loss of power. There's also the age-old method of looking at the speedometer: in a high-speed collision, the return spring tends to fail. Result is the needle gets stuck at the impact speed or close to it.

The 20mph limit is too low. Transportation is for efficiency.
