The crashes I have had have been my fault. Some taxi drivers are a bit aggressive but most of the time its the cyclist moving faster than the vehicle. Most of these cyclics ending up under left turning lorries, I can only assume most of them are stupid enough to try and undertake a truck on a left turn... I saw one accident shortly afterwards and some woman had ended up under a dumper truck at the top of wandsworth bridge road. If you know the junction, its narrow and a sharp left, the truck would have had to take like a racing line around the left corner and the dumb cyclist must have tried to undertake.
