Or the asocial, where you come up to a stop sign, look right, see a guy coming way too fast to stop in time, and don’t go till after he’s blown through the intersection

if it isn’t your turn the car waits, ignores wave, and after a long wait pulls forward very slowly or only if the driver takes over

When BMW comes up with their autopilot, it will handle that situation by ignoring all social cues, or even road rules for that matter and just doing what it likes regardless of anyone else on the road. It will also probably have a little rubber hand permanently giving the middle finger, which can extend and retract from the front of the hood, where the little ornaments used to go.
