London Fixed-gear and Single-speed

Just passed an accident, police were in attendence. A black hatch back facing the wrong way in one lane, with its front bumper/fairing fallen off, a blue BWM diagonally across both lanes, with the police talking to a passenger still in the car. A scooter on it's side with a police person talking to the rider, on the floor - presumably waiting for an ambulance.
There were two bicycles on the ground near the scooter, but I think they had stopped to help, they didn't looked damaged, but the scooter might have clipped them, I guess.

Hope every one is okay. There is going to be a big holdup there for a while.

Odd. They'll keep the roads closed for ages yet any accident investigation will be patchy.
