Fast forward say fifty years until there are nothing but self-driving cars. Assume there will be far fewer accidents ... but there will be some. The question then becomes -- who is liable for such events? The non-driver driver? The car's owner? The car manufacturer (and its AI designers)? Or the government which created the bizarrely non-standard conditions that caused  confusion on the car's navigation system?
