“I just couldn’t have been going as fast as the cop said.”

Oh? You mean that you’re modern car that has an electronically limited top speed of 155 mph just couldn’t have been going 75 in a 50? Or do you think that that cop had something personal against you and decided that he’d risk fabricating an elaborate tale and radar-gun data to prove that you were going 25 over when all the while you were driving the speed limit?
