I used to have a dirt midget. The learning curve is much steeper on a dirt track car. I would think most drivers with the proper training could jump in a 8 or 9 second drag car and be able to use 90% of the cars potential. Very few people could get in midget or 360 sprint car and able to use 50%.

I do like drag racing but it is more about the cars than driving. Drag cars are cooler/nicer than circle track cars.
Also at he end of the season you don't have a beat up, out of date, and worthless hunk of metal.
