the corporate hi-tech "extravaganza" has only come recently with its rise in US popularity. While you are not wrong I think thats just one part of the sport. Indycar is just racing and strategy. F1 is technical development, racing, strategy, and team performance. I like both but while I find the racing better in Indy, I follow F1 much more closely because I really enjoy the technical side of the sport. I also think 10 teams (soon to be 11) and 20 drivers (soon to be 22) that race in every race makes it easier to stay invested throughout the season.
