At Ohsweken they charge $100 for 5 laps in the two seater, and usually have two cars on the track. At times it seems they could do this all night long, as the fans can't get enough of it. Obviously it's not a "race" and the passengers are strapped in with a firesuit and a helmet. The track has a large supply of firesuits and helmets just for this reason. All passengers must be 18 years old. I know they are still moving pretty fast and things can happen. There is only two cars at most on the track.
Yet when I think of some beat up car with a kid in it, I don't think it's too safe. I know pure stocks aren't going to fast, and the chance of a high speed, collapse the rollcage type of crash isn't to likely, I still think it's not the greatest idea around. During an actual race with multiple drivers on the track, I have been at too many accident scenes with flips, fires or hard hits and think it is a great diservice to all involved. For the safety crew to get one person out of a car can be hard enough, now trying to remember what cars have two people in them is a little too much to ask. Just my opinion. I don't care how old they are.
