Well I have done it, but not drunk, the cops pulled up next to us while the music played load as hell and asked us if something was wrong, I did not hear the first time and then said no, just lighting some cigarettes for me and my friend and they then said OK, and drove away, but I do not drink much before I drive and I hate it if someone drives drunk.
If I know I am going to drink very much I stop for the night or leave the car at home.
