My mum drives an auto and I recently visited for over a week and was using her car. My car is manual and the ease of driving an auto is amazing.
The problem I had a few times was when I tried to use my left foot to brake. Since I'm used to using my left foot for clutching I found that instinctively put way too much pressure on the brake and basically slamming on the brakes to a sudden stop! Very dangerous (and scary) but it never happened when there was any car behind me.
One-footed control of the pedals is the best way to drive an auto (for me at least).
Edit: Oh, and I could never start the car if it wasn't in "park" AND with my foot on the brake.
