My educated guess is that everyone not in an autocar is going to interact aggressively with autocars. - They won't play chicken with you. Any dick move you wanna pull in traffic, the autocar is gonna roll over and take it. - You don't have to look them in the eye. That's not a fellow driver you cut off, it's a trillion-dollar corporation. - They're quicker than you and can cope with your bullshit better than your average distracted driver. Shit that would be a guaranteed fender bender is gonna be an autocar slamming on its brakes. - People with money will be driving them for a decade longer than people without money and there will be class issues. Any company launching autocars into a hybrid road system is going to assume all other drivers are not just negligent, they're likely hostile. When you start from a standpoint that every unknown vehicle is going to fuck you over if given half a chance, you end up with defensive programming.
