lol, no kidding, it would be the "change your pants when you finally come to a stop" type of excitement. Probably clean out your seat too. It wouldn't be pretty.
160 is about the fastest I've ever been in a car, and it is quite a rush. I am fairly certain that if I had an accident at that speed, I wouldn't be here talking to you now. Looking back on the incident, it was rather stupid, but I was 19 and in the USMC, so I felt bulletproof. It's probably not something I'd do again in a car which wasn't set up for those kind of speeds...and especially not on the highway, there's just way too much that can go wrong.
