My thoughts: don't stop. If you are riding with people, you don't have to be faster than the cop, just faster than the other drunks. If you do stop in SF, go to court and get it reduced.

I kinda like small town virginia attitudes towards drunk bicycle riding better. I used to work in Culpeper, Va. and the only reason most adults rode bikes was because they wanted to go out drinking and had too many DUIs. Drunk transportation was what bikes were for. We also had an old drunk dude who would cruise around town on a riding lawnmower covered in american flags. The guy was always wasted, but no cop could pull over such a patriotic lawnmower.

/Edit: if you are some place with no traffic, long blocks, no alleys, no one way streets, or if the cop is on a motorcycle... maybe stop.
