So turning right off a major road into a side road, traffic light controlled, I have a green, side road has a red (3 cars waiting happily at the red).
Said cyclist exists side road, through red light right in front of me.
Stop car and get out, he's on the road groaning then gets up and moves to the pavement (despite advice otherwise), clearly off his head on something.
Bike has no lights, he has no helmet, clearly has at least a dislocated finger and broken ankle/leg plus concussion.
Police arrive, statements given, refuses treatment and then tries to cycle home on bike with bent front wheel, bent front forks, bent frame, bent rear wheel and gets nowhere.
In the mean time I have to report it to the insurance company (obviously) and now face the fact that a claim will go on record and the car may be repaired (or written off).
Bloody nightmare.
