That sounds like a cop answer to me! I once knew a cop that would spend his entire shift sitting on the same route every at regular intervals and always ticketed at least four trucks every single time. I could never understand why the drivers wouldn't remember that he is there.Let me guess, and I am trying to quote the police now.
"The answer, boy is about twice as far as you were following that truck in front of you. Don't you know tailgating is frowned upon around here?"
