I think it depends on the type of car and the position of the pedals too. In my Jeep, the pedals are sorta under me, so to speak, and that makes maneuvering with heels easier. When I'm in the sports car, the pedals are more in front of me, and I have a problem with tall heels then. Usually, I just slip off the heels when I think I run the risk of either getting the heel stuck or delaying a brake reaction that might cause an accident.
