I was just saying that sometimes during a race or crash you have no control over your apendages and they can get stuck in the strangest places and then you are along for the ride and you still have to go to work the next day. I remeber racing in an stock car enduro race and window nets wernt mandatory,well I felt the grass on the side of the track as the car was going over and pulled my hand in just as it started to get tight between the ground and the roof. Lucky thing it was a slow rollover(some guy in a big chevy was pushing me over, kind of fun actually)So if the possibility exists that you can get your foot jamed in there I would just put some expanded metal in there so it cant happen.
