and rob you should have told them "no i was going to fast to see the 3 of you"

Well, if they are good, they know something about body language and how to tell if someone is lying. I forget the specifics, but when someone truly doesn't know the answer to a question, and are searching for an answer, their eyes move in one direction (I think up and to the left). If they are lying, their eyes tend to look in a different direction (I think it is up and to the right). If they tell the truth, they look in yet another direction. And if they make something up completely out of the blue, they may look in yet another direction. So, if someone who had been drinking says no, but the cop can see their eyes move in the lying direction, they may continue the questioning and/or field sobriety test. Obviously they won't use it in the courts, but it can be useful.
