Thought you guys might be interested in seeing a bike-camera view of
what it's like to get hit by a car.  The driver was subsequently
arrested.  I have thought more than once that it would be nice to have a
video camera on the bike to capture such an event, or just a driver
acting recklessly or harassing us.   The "hit" takes place at about 2:40
on the video.

"Be careful out there."
