Wow, I forget how different things are abroad. If a traffic cop asked me where I was going, I would tell him it was none of his business. I can't ever remeber a cop asking any questions beyond "Do you know how fast you were going?" or "Do you know why I pulled you over?", followed by "License, insurance and registration."
Aside from fine (which i do complain about a lot, loudly) I don't think American traffic cops are that bad.
