On a another note, I wonder what all these intermediate helper devices will do to peoples driving abilities. We're already getting to a point where more and more people cannot drive a car with a manual transmission. How long before most people cannot park a car or safely change lanes on their own?
I can't see a ban coming anytime soon, but I can see self-driving cars only roads. If you really want to/have to drive yourself feel free to take the 40-50 mph speed limit side roads. Or you can take engage the auto-drive and hop onto the speed limit free express way.
So wait, now that the topic has come to Musk's business, AI is suddenly not that much of a threat? Certainly more trustworthy than human beings, eh?
