I actually witnessed this, and was the one to call the emergency services. Must have been around 8:50 in the morning as I was walking when it happened.
Basically a motorcyclist was travelling eastwards when a car pulled out. The guy smacked into the car and went over his bike, landed on the bonnet and hit the road. I couldn't tell you whose fault it was (if anyones).
The guy was lying on his back, moving his legs and talking but unable to get up. The driver seems fairly shaken up by it. The police and ambulance came, and I gave my details to a policeman and left. Wish I stayed to make sure he was ok, but was already late for a conference by the time I left
