Bob, Is the .75% number based on a day an event or a season?
FYI on the street, there is generally one accident reported per vehicle per 100,000 miles driven per vehicle. Extrapolated, saying most accidents involve two cars, there is an accident (some single cars, some two cars, some multiple cars) there is an accident for every 50,000 miles driven in the US.
Assuming the .75% is based on per event: with an average of 25 miles driven per run session (i feel this number is conservative), four run sessions per day, and 120 cars at an event, and an average of a two day event. 24,000 miles are logged at an event.
If there are .75% incidents per 24,000 track miles that makes an incident expected for every 32,000 miles driven. Yes, an increase compared to road driven miles, but how many road incidents are not reported, and also how few of the on track incidents involve more than one vehicle. (You can't blame the other guy)
Statistically, the risk incurred on track, is 1.56X per mile compared to driving on the street. My average round trip trip length to a track (not including NJMSP) is 450 miles. Statistically, I am more likely to have an incident while in transit than on track.
