I honestly don't care if there are autonomous vehicles on the road, as long as they don't start passing a bunch of laws to either deter people from driving or flat out make it illegal to drive. Elon Musk is high if he thinks we're three years away from a robot takeover of the highways. I would guess that at least 75% of the people between the ages of 40 and 70 (including myself, but not to this extreme) would say, "I'll be god-damned if anyone is going to tell me that I can't drive my car the way I want to or have to over-compensate to accomodate these things." Honestly, if I want to go ten over on the interstate to save myself time, slow down to get a better look at something that I see along the road or jet around someone or something who's/that's driving like a jack@$$, I don't want to run into an "I'm sorry Dave, I'm afraid I can't do that" situation.
