At the age of 18, driving a new Mustang (which was my first car), I was going just over 100mph on Interstate 80 when I lost control of the car and it spun around twice (a 720° rotation) before coming to a stop. I was quite terrified. The only thing of which I can be proud of is that I was alone in the car, I did not risk anybody else's life seeing how fast the car would go. It was about 3am and the highway was empty of other cars.
What is the fastest you have ever driven?
