Why were you then unfair in your post?
What part is unfair? Formula One cars exploding into carbon fiber? It's what they do when they get bumped. That doesn't change the fact they're far more impressive on a track than a NASCAR. NASCAR is fun in its own way. Big, heavy, lots of steel, V-8s that make less power than Supras I've driven, but much more aggressive driving thanks to the closed wheels.
IRL is neither of those. It's roundy-rounds in cars that can't push on each other. While I still watch the Daytona 500 each year, the league deserves contempt. They've done more to neuter and stifle innovation than any other series. If the other guys can't keep up, they pressure the promoter, and your tech gets banned. They did it to AWD, side-by-side configurations, and turbines, all of which were faster, but safer cars. Such a shame.
