Ive always driven an automatic with 1 foot. Especially after driving behind my grandfather years ago who drove with 2 feet, and constantly watching his brake lights flicker on and off... It drove me crazy and I always swore I would never be a "2 foot driver".. lol
Ive been driving both autos and manuals for years and have grown to automatically "adjust" my driving style based on what kind of car Im in. So no problems for me with an itchy left foot in an automatic... It enjoys the time off.
