Niether one is legal. If you are sprinting around it's called public intoxication. Besides, you are making the argument right now that bikes shouldn't be considered vehicles. Regardless if you choose to ride or drive at 10-12 mph you are making the choice to do so, the capacity for the vehicle to go much faster is there. Most of the time a pedestrian is going to be much slower than someone on a bike. I do agree, as I mentioned, that the penalty was likely too harsh in this instance. I also agree, at least in theory, that the penalties for riding while drunk should be less than for driving while drunk. All the same, I have no problem with a law being on the books which makes it illegal. It's stupid and dangerous and should be avoided. Take a pedicab home or make other arrangements. It's not that hard.
