Imagine an F1 car being entered at the the Indy 500. The same power, but half the weight!
Very hi-tech. This is where you find technologies that make it into street cars 10-20 years later. ABS, Traction Control, Wet tires, clutchless trannies, active suspension, independant suspension, turbochargers, etc. etc. were all pioneered in F1 long before they appeared on the road.
Indy cars, as far as I know, have evolved very little in the past 10-20 years. A little tweaking here and there. But I haven't followed it that closely, so maybe someone can tell me different.
F1 cars are constantly evolving. In the 1980's, turbos were allowed, and these little cars weighing only 1000 or 1200 pounds were producing 1300 to 1400 horsepower during qualifying!!! They had big slick tires, big wings etc. Today, turbos are gone, and their power is limited to around 700-800 hp. Their wing size have been reduced, ground effects have been limited, and slicks are no longer allowed, but todays F1 cars are faster than the ones with all the toys in the 80's.
F1 is geared to road courses. While visually more interesting, it's true that it it makes passing difficult. That's where skill comes to play. On a big banked oval, if you have a faster car, you're going to win. In F1, having a fast car helps, but the driver's skill, and the speed and effectiveness of the support team is critical.
The nice thing about F1 is that it is so varied, and not U.S.-centric. The mentalities and styles between drivers are so different. I used to love to watch drivers like Alain "the Professor" Prost. Always exact, no mistakes, always perfect, and holding the car stable. M. Schumacher is a bit like that. Ayrton Senna was his complete opposite - hanging the car on the ragged edge, and sometimes beyond, winning because he was willing to push himself harder than everyone else. Watching him in a race under heavy rain was amazing - within a few minutes he would have lapped the slower drivers, and would be miles ahead of anyone behind him. I miss watching Senna. In fact, I stopped watching F1 for several years after I saw him die in 1994.
Also F1 races are generally shorter with a maximum 2-hour time limit, and slower because of all the turns. I think 2-3 hours of constant high speed is boring.
