So I'm thinking the idea of piss or shit your pants must come from non-racers.
Never had it happen, never seen it happen.
Once things go wrong it does seem like time slows down and everything is in slow motion.
At this point you have no control over anything and are along for the ride.
Mostly you are thinking...Oh crap, this is gonna hurt along with waiting for what seems like forever for it to be over.
Given all the car and bike racing that happens ever weekend I wonder if is safer that most other things in life.
Many, many crashes that people walk away from thanks to safety rules. Other hand people trip on stairs not using the handrail, fall down in the shower...
Indy cars have always had a problem protecting your feet and lower legs.
Every crash is studied and new rules put in. Much progress has been made.
