I saw the darndest thing on my ride to work today. So I was stopped at a light downtown and I saw this dude riding real slow on the sidewalk across the intersection from me. He appeared to be riding brakeless. Perfectly normal. That is, until I see this guy coast across the street and hop of the moving bike...

Here I am thinking riding brakeless fixed without foot retention is crazy but come on. Is this a thing that you guys have seen other people do? Has anyone tried it? Or is this guy just some weird unicorn?
