Mine was rather painful.
I was right hooked at 15mph in a bike lane. I was beside the car when it happened and I impacted her right front tire.
The end result after a terrible superman impersonation was a free ambulance ride to denver health.
I tore open my left knee cap, bruised every limb and both hands, scrapped up every limb, and broke my right radial head.
A month later I was on my trainer. A month after that I was riding again. Yet another month later I was riding the triple bypass. What doesn't kill you ...
