I make a habit out of watching the show COPS, and counting all the things that are done wrong by (sometimes) the police and (most of the time) by the suspects. I really have always found it amazing how many people will let the police search their car during a traffic stop because they asked to.
Darnell Dockett of the Arizona Cardinals, however, refuses to be played in such a way. (HT: EDSBS)
I remember the first time I refused a search during a traffic stop, even the officer was like "Really? Wow. Well, you're within your rights to refuse."
