4 will happen sooner? Doubtful. Get out of US cities. People love their cars and as such, mechanics just like plumbers and electricians are going to be around for years. There will not be a predominance of consumer owned self driving cars in my lifetime, despite what Tesla, etc. think. Just like how most rail transit in the US makes little sense due to lack of density, the autonomous car won't appeal to everyone due to lack of use, want of control, etc. As such, mechanics will be around for a long while. People buy vehicles like Toyota Tacomas and will own them for 20+ years. I see that not changing with the 2016s, despite all the announcements of every major automotive company working on autonomous cars. Maybe in major cities in the US (maybe) and maybe in parts of Europe. But I don't see it. It's about as farcical as door to door delivery by drone with Amazon. Looks great in theory, practice (and practicality) not really once you dig into it.
