When A Cop Pulls You Over, What Do You Say?

Of course, Cops ask stupid questions when they pull people over. And we are forced to give the wrong answer as there is no RIGHT answer.

For example, a cop pulls you over and inevitably says, "Do you know how fast you were going?"

How does one answer this? If I say "no" then it looks like I'm a careless and reckless driver with no conscious idea of what I'm doing. If I say "yes" then it looks like I'm deliberatly thumbing my nose at the law. In either case, I am forced to incriminate myself. But we can't exercise our Constitutional right to silence either because that would make us look even more guilty.

Perhaps honesty if the best policy. "Yes sir. I was going 90MPH in a 35MPH lane. Please write me a ticket and bring me to jail."

Nah! That won't work. Anyone have any suggestions?
