> Self driving cars will obey all local traffic laws

I doubt it. I don't think consumers would tolerate a car that always obeyed the speed limit. And if a self-driving car did, it could be pulled over for impeding traffic.

Do you hate trains that obey speed limits?

Speed limits can be changed to something more reasonable, and humans won't worry about the speed it goes but the time and cost.
