Dirt:
1. More passing
2. More Cars- Have to race to make feature
3. Can see what the driver is doing
4. Money vs speed- Seems like in the wing cars there is a huge differance in speed from 1st to last or even 1st to 10th.
5. Don't need a 5th

Asphault: I'll take the wings over nonwings anyday (except the little 500)
1. MORE PASSING
2. MORE CARS
3. SPEED
4. Side By side racing, no follow the leader stuff!
5. The unknown
