I got pulled over for doing 102mph on the Tamiami Trail in Florida a few years back. I was on one of the utterly empty and straight sections, with no other cars heading in my direction, and with a big run-off on each side.
The other direction was well separated from mine, so I set the cruise control at 100, and just concentrated on keeping going straight.
What I had not realised was that in the US a police car coming the other way is able to check your speed (here in the UK, the are not allowed to do that), and so I was caught.
On the plus side, the female officer was absolutely stunning, and very kindly marked down the speed I'd been doing to let me continue on my way to catch my flight back to Europe.
Despite my having done this is a truly horrible car (Chrysler Sebring), I can't say that I'd accept that it was unsafe at any point. Illegal, yes, but that's a different question.
