They can use it to start fixing the roads, not the cars.

Just look at the cross intersection they use as an example, typical of the US. The ROAD is the death trap there. People are crossing each other at high speed, this is the BUG, and should be fixed.

The proper solution is putting there a roundabout, and you will have instantly less fatal accidents.

The US was the first to use roundabouts, but those early designs did not work well, and as a result we have those monstrosities like in the picture all around the US.

With electric cars that record accidents, the first bugs that we should fix are those in the roads, like those concrete barriers that have no smooth transition but a front wall out of nowhere.
