if you feel bad then dont ask. its pretty cut and dry man. you let him drive your car, shit happens on the track. be glad it was just a bumper. the situation sucks yea but this is what you deal with being on the track.
either man up and ask for money from him. or be a cool guy and take the two free days that was awesome enough to be offered. a few tracks i know would have said fuck off and have a nice day.
