The below candidate has no connection to cycling whatsoever.

Several years ago I was driving my cage late at night (~230 AM) on a rather busy - 4 lanes in each direction, 50 MPH speed limit - and I noticed an impaired woman (I assume drug addict, by her appearance and behavior) staggering through the middle of the leftmost lane against traffic in the direction I was traveling. I slowed down to ask if she was OK, got a shoe thrown at my car and cussed out. She has been my perennial Darwin candidate ever since.
