The inability to do a rolling start in an automatic really bugs me after being used to manuals my whole life.

I switched to an auto a few years back for reasons (UK, still not super popular here), and once or twice I've had the car cut out on me at speed, in traffic; had it been a manual, I could have just restarted it while moving, but it forces you to be stopped, foot on the brake and in park before you can push the button to start it.
