But why?
The point of these laws for cars is that cars can absolutely kill innocent people if the driver is inhibited in some way. The chance that I'll kill someone else on a bicycle is so remote it's a rounding error. Oh, and hit and runs aren't really a thing on bicycles because if I hit someone, I'm going down too and it'll take some time for me to make a getaway (and I'm not getting away that quickly).
If we jail people for riding drunk, wouldn't that just encourage them to drive instead? If you'll go to jail anyway if you're caught, might as well get home faster, right?
