Driving with 2 feet should only be done when the car is equiped with a clutch. A lot of people believe it is safe but it isn’t. Most reasons have been addressed here already. Actually, many people fail a driving test because they drive with 2 feet. The teens down the street were taught by their grandmother to drive that way and everyone of them failed the driving test for that reason. Grandma was furious and let everyone know about it. Well, just a couple of months ago she drove through a retaining wall at the bank drive through. Her oldest teenage granddaughter was in the front seat and told the police that when grandma tried to stop she mashed down with both feet but one was on the brake and one was on the accelerator. Grandma swore that she had both feet on the brake. The tire marks on the road backed up the granddaughter’s version. The granddaughter told my son that now she sees the reason for learning to drive with one foot and is now driving that way. Some people will always believe they are right even when told several valid reasons for doing things a certain way.
