We can always use a little reminder to remain visible and defensive while riding.
Heather Butcher (a pro triathlete) was hit while biking after a left-turning (US) driver failed to give her the right of way. The other car appearantly did not stop at a stop sign and collided with her front tire. She is facing surgery today to repair a badly broken wrist. Her bike was destroyed.
The driver, what did he get? A TICKET FOR RECKLESS DRIVING! At least she will be able to ride again in the future. It could have been much worse.
