80s/90s. No doubt auto-driving tech is going to trickle down to the mainstream in the next 15 years, but I doubt it will change so drastically.
The proponents of this industry change in the next decade seem to believe that the people in the US simply drive/own a car to get from point A to point B and they would us "mass transit" if it was available and convenient in their area.
This is simply not the case. All one needs to do is look at I15 this weekend at all the trucks, boats, jeeps, trailers, RVs, motorhomes, and other toys to realize that it just ain't gonna happen overnight.
Who knows, maybe in 10 years "google" will have a program that will drive my 3/4-ton truck with trailer in tow, back it into a remote campground, drive my Jeep to Golden Spike and then proceed to auto-drive me through the crack.
Will there be some form of auto and manual drivers on the road? Quite possibly. But wholesale industry changes? Yeah, about as much wholesale industry change as hybrid technology was supposed to do by 2020...
