I used to see this guy riding around near my office in Boston. I have a great amount of respect for most folks who tinker and listen to a different drumbeat, but why the hell you'd want to produce this monstrosity is beyond me.

Drastically limit vision on one side (unless your head rotates like in The Exorcist) and make turning left a completely different physical experience than turning right?!

Every time I saw the guy I'd be amazed another day went by he wasn't creamed in traffic.
