like many people I watched the media circus over Uber starting self driving car service in Pittsburg. It has been quite a few days and the media hasn't been able to gin up a follow up about a car or person being hit or a car getting lost. I know they have engineers riding along, but it still is impressive. Also I noticed their "hats" on several different models. This indicates Uber has a system that retrofits on a lot of existing models. Eventually the government might insist on a standard, universal system ( anyone remember the mandate for sealed beam headlights?). Right now Uber would be in the lead.
