this is awesome and seems like a great start but it looks like there will be a lot of issues with it.
1) when it's pulling out, seems like there will be a higher risk of an accident since it is more difficult for a the car to "see" another oncoming vehicle than a human
2) look slow as fuck, which would piss off other drivers but could be pretty funny
3) what happens when it gets in an accident with another car? the other person would have to wait for the owner to return so they could exchange info etc.
Just some thoughts
