I did way back when I was 18/19... I was riding my bike home from work, and a cop directing traffic yelled at me to get out of the street. Without even thinking, I yelled back "go fuck yourself". He called to his partner across the intersection, "Mike, get him!". Mike was on a motorcycle. I was sure I was fucked, but I knew the neighborhood, so after salmoning up a one way street full of double parked cars, and taking a couple turns, one being into a narrow alley that's almost invisible unless you already know it's there, I got behind him - figured that was the best place to be... He never looked back, just slowed down, looking in doorways, between/under parked cars, until I got within a couple blocks of my house, then I hauled ass and locked myself (and bike) in the basement for the next half hour.
Yeah, this was in Boston, Beacon Hill to be specific, not known for wide sidewalks... I was in good shape in those days, I could cruise all day at 15mph, for my half hour commute I could maintain 20mph easily, I would pass cars pretty much continuously in downtown areas, the street was where I belonged...
