One of my colleagues at the after school club I work at was knocked off her bike by a motorist this morning. She's not badly hurt, but naturally very shaken up.
She'd been waiting to turn right into the school, and as the oncoming traffic cleared, the driver behind her undertook, then swerved right and clipped her bike, knocking her off the bike into the oncoming lane. It was clear for long enough for her to scramble out the way, but he was gone.
It's pretty hard to square his manoeuvre with anything but a malicious attempt to teach a cyclist a lesson. There's no way he can't have seen her since he was held up by her in the first place, the presumable cause of his aggression.
She took his registration, though, and the police have been pretty diligent; came to examine her bike after they'd interviewed her, and are hopefully now throwing books at him.
