Car Does Sewer Tunnel Loop

Faster would be better.

That's what I was thinking.

Actually, I'd like to see a real life experiment filmed on the theory that an F1 or Indy Car can drive upside down due to speed and the sheer downforce the aerodynamics produce. THAT would be impressive to watch.

there's no point in speed where wind resistance can match the sheer weight of a car, You'd fall like a rock or a bullet...

I think I did see footage of an indy-car driving upside down once. But I don't know if that was real or CGI...

There are indeed f1's that can drive upside down because of the way they tunnel air underneath them. Plus you can add stuff like fans to keep it up. The only thing you need is speed to keep the air moving.

The engineering in those things is beyond superior.
