I doubt people will be able to own self driving cars. They are going to need the maintenance schedules of small aircraft to be safe. It's more likely they'll only be available as a service or taxi.

I also think this is a big reason for the apprehension of self driving cars. While some advocate safety, people are more than familiar with software bugs in our phones, computers and web apps.

Sure there is a difference. The software in mission critical applications like pacemakers, aircraft navigation, etc. has to be thoroughly tested and designed to be either failure proof or failing in a safe way or having a redundant system. But will the products Uber and Google develop have the same level of testing Boeing puts into aircraft or SpaceX puts into rockets?
