So in that link the guy goes round the loop at 36mph (58km), and experiences 6Gs?! It was said above that even fighter pilots are only trained up to 7Gs before they start to red out. How are the Gs so high when the car’s going round a relatively small loop at a low speed?

God, I remember that commercial! The 1984 Ford Tempo…being hailed as a technological masterpiece…hilarious now, in retrospect. That car was a POS!

I think the widespread success of [roller coaster loops](http://en.wikipedia.org/wiki/Vertical_loop) provides further evidence that you could.
