I think autonomous cars are something that must happen, and the sooner the better, but I am also a bit concerned that they could represent the ultimate weapon if a malicious actor gained control over them. One battery fire isn't a problem, but if every 2nd car in a city or country crashes into something in a way that starts a fire, that becomes a very big problem extremely quickly.
