Whenever I drive an automatic (my truck) I always brake with my left foot. I'm not sure why I started doing it but I've been doing it for the last 15 years or so. I don't ride the brake pedal though, just like I don't drive around riding the clutch pedal...
I do this with an auto as well.
OP: Wery wery baaad.
