BTW, if I was potentially faced with such a massive fine, I wouldn't even stop. I'd just keep my foot on the floor and have a good chance of getting away. Try and catch up to a 250kpm car from a standstill before he gets to an exit of some sort.

What really is the extra risk at that point? I'd rather make them catch me or prove it then willingly accept such punishment. How much worse could it get by saying you didn't see the cop motion you to stop? You were already braking the law. Keep breaking it.
