Why can’t we all just get along? I grew up being a big fan of F1, NHRA, SCCA, and NASCAR, and have campaigned cars in both NHRA and SCCA. No problem with diversity here!
You left out IMSA, WRC, and FIA GT and WTCC. You, sir, need further motorsports diversity training. :)
Straight-line, roundy-rounds, twisty-turnies, asphalt, dirt, mixed, all forms - go Go GO! Hell, I've even watch huge trucks racing across the desert using GPS waypoints to get to the finish line. It's a blast - three-man crews, when them suckers break, they break big.
