ok, while i agree that cycling while intoxicated is not the smartest thing to do and it is possible that you could injure someone else, for the most part you are only endangering yourself...

thus, there is absolutely no comparison between driving a car while drunk (which is a horribly bad unsafe act and socially wrong) and cycling while drunk (which is basically kind of dumb)

back in college i rode my bike while over the legally drunk level but still pretty in control maybe 10 times...

once i was so drunk i could hardly walk and cycling was like flying... it was late at night (maybe 3am) so the streets were deserted and i would be riding along and then notice "hm, my legs won't move" and then realize it was because i was lying on the ground... and then my eyes would focus and i could see i was lying face first on the pavement... i think i fell maybe 10 times in about 1 mile home and ruined my jeans and skinned my hands a little. i rode slowly and sure, i could have hurt myself worse, but compared to my many drunk buds who were piloting huge steel cages around and endangering other people (or riding with such people), i consider what i did comparatively safe... (as far as endangering yourself, people frequently injure themselves quite severly walking drunk and tripping or whatever --- it's the getting sloshed that really creates most of the danger --- but then driving a car extends the danger to other people) -- i think my biggest real danger as a drunk cyclist was danger from the drunk auto drivers... (and yes, if sober i could better avoid those guys too)

not seeing a stop sign or a curve on a bike is dangerous to the cyclist, but not seeing a stop sign or a curve in a car often results in a car in a living room or a few people being run over...

drunk auto drivers kill hundreds of people per year... how many people are killed by drunk cyclists? it's just simply not in the same league of danger or 'social wrong'

in my teen crazy years i only drove a car once while kind-of drunk (2am in the country but it was stupid anyway) and maybe twice while near the legal level AND i will NEVER drive a car drunk again - but even now if i were not totally sloshed and the distance were short, i would not rule out cycling... (i drink rather infrequently these days and to excess maybe only once a year so it's pretty unlikely)
