Why don’t we have cars talk to each other and coordinate their routing? Like some sort of peer to peer mechanism that helps them not crash each other. Why can’t vehicles be made to stop at cross walks when someone is crossing with some sort of communication to the vehicle?

There is a long and glorious research bibliography on v2v comms for this purpose :-) The obstacles are pretty obvious, the chicken-and-egg problem and trust.

Solve this problem and LA traffic will get much better
