The only reason you need is side by side racing and passing but if you must have five then here you go

1. side by side racing and passing
2. you actually have to drive the car, instead of just stand on the gas and go
3.I live in the middle of sprint car country and can see a non-wing race 3 times a week, some times more
4. You get to see the drivers compete every week and can see them drive the car
5. Alot cheaper to watch, every wing show is a special event show, with outragous pricing. (IE: Outlaws = $30 tickets) I can get me and the wife into the track for that
