All motion is more dangerous while drunk, but how drunk you are matters, how fast you're going matters, and how dense traffic is matters. I'm not convinced of how much more dangerous biking is while mildly drunk than walking, or biking very slowly while very drunk, especially at night when almost no one is walking.

So is walking anywhere

What is your point then, if not “cycling drunk is as likely to kill somebody else as driving drunk?” If it is “it’s technically possible to kill somebody cycling drunk” - then yes, I concede the point. But it’s not a useful point in this discussion.

People sometimes die due to collisions pedestrians.

Should it be illegal for people to walk around drunk as well?
