The thing they need to do is to not use so many bloody tracks in the D class series. I'll repost what I said on the forums:
Personally I think all the D class roadies should double-up on the purchased tracks to control costs. For instance, buying Watkins then running the boot configuration and the cup configuration later on in the series. It allows people to run the series for half price essentially. Somewhat like the Spec Racer only less extreme.
1. Mid Ohio full no chicane
2. Sebring Club
3. VIR North
4. Watkins Glen Classic Boot
5. Lime Rock no chicane
6. Barber Short A
7. Laguna Seca
8. Sebring Modified
9. VIR South
10. Mid Ohio short
11. Barber Full
12. Watkins Glen Cup
That cuts the entry cost down from 120 or so to about 70. AND we get to run the little short configurations that seem unused. That initial bump up to a full season in D is the most expensive single moment in most drivers careers.
Also, Mid Ohio. Go watch. Nowz.
