altering your state of consciousness... moving at high speeds... being in traffic... none of those things go together.
All cyclists do at least two of those things at the same time every day.
Seriously though, I doubt most people are hauling ass through the main corridors of the city during rush-hour, while drunk. Usually its people meandering down the side-streets bumping into fire hydrants.
I've said it before, driving drunk isn't safe, biking drunk isn't safe, and in some circumstances, walking drunk isn't safe, but at least with the second two, the only person you are gonna hurt is yourself, and while I've lost a lot of rights here, the right to hurt myself is one I will defend until the bitter end.
I'd never recommend that people drink and ride, but sometimes it happens, and whadayagonnadoaboutit? Just laugh along, I suppose.
peace,
