I’ve never owned an auto, only manuals. But there’s been a couple times when I drove automatics for friends and family and accidently slammed my left foot into the floor or brake due to muscle memory. The pedals are close together in modern manual cars so you can heal toe, and automatic gas pedals are nearly always wider, because why wouldn’t they be?

So yeah, not only do I believe op drives a manual, I bet they do it often enough that when they do drive an auto they have to consciously hold their left foot back. I know I have to. I’ve been using a clutch too long, my left foot just wants to go.
