@MicroSFF I truly hope autonomous cars don't develop the human "everyone else is there, so it must be good" instinct!

But then again, a traffic jam on a freeway is mostly annoying because you have to constantly be paying attention. If cars wanted to toodle along chatting with each other, where's the harm? Especially since they could warn incoming cars to exit before hitting the jam if their passengers were in a hurry, and probably even shift around to let one car out if they needed.
