I don't think those devices reduce the number of accidents, so I disagree with your premise. I think they serve to help slowly roll out self-driving capabilities.

Good for you. But society disagrees and requires them.

People in society are disagreeing about the accuracy of the devices and arguing about it. Kinda circular logic to insist that "this law is about the be passed, therefore it's the will of society, and therefore is correct."

There was also a time where people suggested that vehicles replacing horses was unsafe. They were, of course, correct in a sense, but tended to ignore the decrease in horse related accidents. There was also a time where quite a number of people believed that the human body couldn't cope with speeds over some arbitrary number. They also were proven to be incorrect - mainly because technology enabled people to travel faster and then subsequently made that travel safer.

Do you have a source for this?

I don't know of any comprehensive studies that have been published one way or the other. I know sometimes the computer causes accidents and sometimes they help prevent them. That said, I've yet to see anything that indicates they prevent an appreciable number of accidents - it's usually pitched as driver convenience and data collection for self-driving.
