I'm going to be the voice of dissent here. I do not like Tilke tracks. They are like Supercross tracks in that they consist of the same corners, straights and such. The only difference between tracks is what order the turns and straights come in. Austin is not all that great. First off the straight from the starting grid to the first corner should have been downhill. That way we could see who has the best braking skills, and who has nerves of steel. And since it is an American track it should of had the one feature that is uniquely American, a high banked high speed turn. IMO the designers missed a golden opportunity to build a one of a kind track. I like tracks that take advantage of natural terrain. Austin had nothing to offer in that respect. The natural terrain is flat as a pancake. Tracks like Spa, Road America, and Sonoma, (The full course, not what Nascar runs.) are very entertaining. You cant see the whole track but you do see enough to make it worth going. Street courses are a complete waste of time and effort. They are too narrow and way too bumpy. How many cars have been destroyed because of that combination. Ovals can make for good racing, like Indy and the once great Ontario Motor Speedway. Tracks like Daytona, Michigan, and Talladega bore me to death. There were, at one time, dirt road courses. Yes, believe it or not. You want to talk about some entertaining racing, that right there is it. It reminded me of some of the roads we had in rural Tennessee. I completely agree with RP King that the more varied tracks drivers race on, the better you can see who has the best skills. Now that I have finished my rant, I can answer the OP's question. Euro type tracks make for excellent racing. Unless you have variety it's hard to discern who the better drivers are. Thanks to everyone for putting up with me. Have a safe run to the checkers. Oh, one more thing. The NSA can kiss my a$$.
