Some drivers just can’t adapt. It is like a right-footed person trying to kick a soccer ball with their left. I sort of see what they mean, you have a lot less feeling and strength in your left foot. Rubens said he couldn’t change to left-foot since he had been using his right foot for years and just didn’t have the same feel with his left. I guess it is something you build up over time and it would feel weird. There isn’t a lot of travel in those pedals so you need to be ultra-accurate.
Besides, I doubt they really know what Schumacher was doing, the conclusion may have been that he is just a better driver and not because of his two-footed action. I remember taking a rally driving course in the mid-90s where I was told to never, ever left foot brake. Same with not hitting both pedals together in go-karts! Anybody else get this?
I thought the go-kart guy was concerned about wear, but he was serious about lifting from one pedal and applying the other, never both. He said ‘thats why you do that in a car as well’ – so it wasn’t that long ago that left-foot braking and not riding both pedals was very much the norm.
