Racing was when a few guys got together and built a car with the idea of going faster than everybody else on the track. The engine guy spent all winter on the dyno trying to find 5 or 10 more horsepower, while the chassis guy was welding up his new design himself.
Today a millionaire buys one of the one or two "approved" chassis, and installs one of the one or two "approved" engines, which is sealed so his mechanic can't even try to improve it's performance, why that would be cheating! Then a bunch of the identical "approved" cars run a 500 mile economy run to see who will have enough fuel to finish. The so called race is won or lost by decisions on when or when not to pit.
On the news last night they announced the winner of the Indy 500, and not only was it a name I'd never heard and couldn't pronounce, I find out he was a three time winner, and again I didn't even remember ever hearing his name before!
