I'd buy one
I wouldn't be an early adopter as I'd want to see some data first, but while I enjoy driving sometimes the times when I don't easily outweigh the times that I do so I'd make the trade. Being able to do something else while going from A to B would be nice.
However, I think Tim 11 is being wildly optimistic if he thinks there's even a 0.000000001% chance that driverless cars are ALREADY safer than human drivers. He's really buying into the Google propaganda machine, that's for sure! They probably are safer than humans, in the limited contexts in which Google drives. The roads in California are way better than in much of the US, let alone the rest of the world. Let's see how it does on roads where the lane markings are gone, on gravel or dirt roads, on poorly marked construction areas (I've driven in the wrong place and had to back up before, if it confuses me no way software will get that right every time) How about on roads with several inches of fresh snow, no curbs and only the outlines of the ditches on either side and the occasional sign to give you a clue where it is?
They will come in stages, and first be approved on interstates (freeways) in the US. Those are well controlled with defined entrances and exits, generally well maintained, have reflective markers on the sides of the road, and traffic is all moving in the same direction. It will prove itself there and progressively be approved in different areas. It will be at least a decade from the interstate approval before they get general nationwide approval to drive anywhere a human driver is allowed to drive.
Biting the hand that feeds IT
