I am surprised that this has gone on for 11 pages

I have trouble staying on a bike sober never mind trying it when I'm legless.
The law is pretty clear regarding bikes and drinking. I cannot see why the same rules dont apply to cyclists. Admittedly, a collision with a cyclists and pedestrian do not often have the same impact as a car and a pedestrian, but it has in the past and I am sure, will do again.
When a cyclist goes out with the idea of going out for a few beers and then riding home, they know at the outset that they are not going to be in a fit state to control the bike as it would be normally. All it needs is for them to wobble or swerve and then a car to take action to avoid them and then disaster could strike without the bike hitting anything at all.
I am not going to try to justify drinking and riding a bike just because I am a cyclist. If you want to go out on the beer, get a lift, walk, use a taxi or a bus.
Otherwise if you get caught, dont cry about it. You know the consequences.
