And now, an idiot doing a kamikaze run downhill at 80 mph on a moped. When I had my off on my bicycle last month, I was doing about 20 mph. I skidded down the asphalt for (when I went back later and measured) about thirty feet, ripped up a bunch of gear, got nasty road rash, and either tore rib cartilage or cracked one outright. It's still sore. On the bright side, falling off here, well, it wouldn't be quick, but it'd be final.
