Well, I do not ride the brakes, and have never had a problem using my left foot on the brake. I accidently let my licence expire some year back, took my driver’s test driving with both feet and passed just fine. I even reminded the Officer that I used both feet and he told me to drive however I wanted to. It is so simple, the right foot to go and the left foot to stop. It is possible that one might get confused while driving a stick, but I hate stick shifts and avoid them. Thanks for hearing me out!!!
