I've always made it a rule of thumb to never go more than 25 over, more than that and its reckless driving for many states if they want to push it. The time I do decide to unleash it I have to feel nearly 100% certain there is no risks, ie.. traffic, clear road, visibity clear and open just in case smoky is hiding in the trees and what not.
SURE...Go directly to jail, do not pass go... wow...
Doesn't matter to me anyway, I only go the speed limit.
What, you don't like smoky????
