Heard an interesting fact on a TV program about indy cars. They create enough down-draft at 100 m.p.h. to keep themselves on the track if it were upside down.
Could this be a new "extreme" sport? At the end of the onramp to the track, the track flips over? J/K of course, but that was a fact I never heard before. Am I the only one?

 

Ya, the F50's rear wing generates enough downforce at 110mph (or so) to do the same thing - upside down driving.

It would definitely be a badass x-game

 

F-Zero and Wipeout are the future of motorsports.

 

Yeah, F1 cars have more downforce than the car weighs at highspeed, that's why they can pull 2-3gs laterally in corners and brake up to 4gs. I have often thought how cool it would be to flip the track over and see the car sucked to the road upside down......but then I thought, uh oh.....what happens when they begin braking for a corner. I had that image of the Wiley E Coyote's face just before he fell into the canyon from running off a cliff

 

It'd work fine for something shitty like NASCAR. Mebbe that would actually make it worth watching.
