How big is the fleet of autonomous cars? A handful; the best I can find is it's a bit more than 10 cars. Let's call it 11 for simplicity.

Are you going to be a passenger on an airplane that is likely to have an accident once every 6 years?

I wonder how well an unmanned aircraft or single pilot would've been able to handle the wheels up landing that occurred yesterday at LAX. I am sure those 41 people in the back appreciated having 2 qualified pilots up front. Those pilots did an outstanding job.
