Over the years, I've had over a dozen friends that ride bikes suffer injuries in motorcycle accidents, and almost none of them were at fault.
Once I was a passenger on a bike that was being driven by a friend who was a motorcycle safety instructor, and he expertly laid his bike down when a car suddenly pulled into the street from a blind alley, blocking our path and making some sort of collision inevitable (I still caught my ankle in the spokes, which cut into my military boots, bruising my ankle up pretty good).
Even though we were not at fault, that pretty much cured my fascination for driving in traffic with motorcycles (I still occasionally ride off-road with friends on their bikes - I only own a 10-speed racer and mountain bike now).
Wishing Tom a speedy and full recovery!
