I flipped over the car and set it on fire
How did you manage to flip a car by yourself?
I went 80 miles per hour over the speed limit and forced the car to flip itself over.
I don't know what you are talking about, but no matter the circumstances, it is wrong to vandalize and set fire to other people's property. You could be arrested for this act.
I was simply just testing my limits.
Whatever your intentions were, this was a malicious act and it was very illegal. You had nothing to gain from damaging this car, but you could face severe consequences for doing so. I hope that you learn not to do things like this in the future.
