Agree about BMW drivers.
Subaru drivers, however, are far worse ... at least here in Northern California. The clueless idiots think they are invincible.
Self driving cars? Do not want. I know too much about computers & programmer error. To say nothing about software variability between multi-billion-dollar multinational corporations ... can you "self driving car" proponents HONESTLY show me that Ford, GM, Toyota, Nissan, Volvo, Fiat, Honda, BMW, Mercedes (google), et alia will all play together nicely on the open road?
Apple, MS and un*x certainly don't ... There are risks, and then there are risks. Self driving cars are a risk I don't really want to see when out & about.
 I said "show". Don't tell me, show me.
