An idea that's asking for trouble..

[xxxalexxxx]

in theory it sounds like a nice idea but people are gonna be pissed that they're getting pulled over ( because they'll be late for work, school, ect.)....people don't generally want to be bothered and pulled over for any reason because most of us have places to be at certain times ...so i have a feeling this is gonna get ugly lol

I don't even drink coffee. I like my O.J. in the morning. I would be pissed if they pulled me over and made me late for work. Stupid idea. How about a discount on my next insurance bill, now that's a good idea.

I'm not sure how the police can pull you over for being a good driver. I would think they would have to have probable cause that you committed a crime to pull you over.
Maybe they have a way to indicate that pulling over to get your free coupon is optional?
If not, I think they have some serious legal issues to deal with IMHO.
