Yes, I think that eventually self-driving cars will be safer, faster, and work better in heavy traffic. If they can all talk to each other then they can drive at high speed, bumper to bumper, and coordinate lane changes, communicate road hazards, and stuff like that. But I also think we're a long way from that reality. As long as human drivers are on the road, the autonomous cars and trucks will still have to follow the basic rules that humans do, and be able to react to the unpredictable driving of bad drivers. I live in Washington, and it seems like about 95% of the people on the road here never even went through any sort of drive your streaming or driver's ed. These are the worst drivers I've ever seen, anywhere.
