Apparently the Fiat 500 has a feature that nearly disables the engine when the brake and accelerator are depressed at the same time on automatic transmission models.

I found this out when I was riding with a friend that owns one. He had to stop, turn the engine off and on again to reset this condition.

I mentioned to him that if he used his right foot only to brake and accelerate then he would not have to worry about it.

This begs the question as to how many people out there are left foot brakers. I personally don't know how ANYONE could get into this habit at all. I learned to drive using a manual transmission, so the left foot was clutch only. When I started buying automatic transmission cars, the left foot is just along for the ride.
