I've personally seen a few "self-driving cars" on the streets of SF and I suspect many of you reading this have as well (particularly if you live in the Mission or South Park).
Just last year I was talkng with engineers at the self-driving car company "Cruise" which had a free internal app to taxi employees around with a self-driving car. I personally saw the tech demoed. One of the engineers called one up to go drinking the weekend prior (sans drinking buddies - company policy). He claimed his coworkers come to work in them occasionally. The cars and engineers could be a grand charade but it seems like "self-driving cars" are already used by non-daredevils every weekday.
I learned to drive on backroads of rural Colorado; It may be these cars are safer than I in the sometimes "adverse" driving conditions of San Francisco.
Is this really how a distant technology looks?
