Here is video of a motorcyclist hitting a cyclist. Luckily, no one was seriously hurt. That aside, from the video it looks as if the motorcyclist intentionally struck the cyclists because (1) motor man appears to have a clear view of the cyclists in front of him when the motor man comes around the corner and, (2) while the motor man may be sticking out his foot to stay upright, it looks more like the motor man kicks at the cyclist just before impact.
Just goes to show that you when operating a vehicle on the road (bike, car, motorcycle), no matter how safe you are operating, you still cannot control the biggest factor that leads to accidents- OTHER operators.
Stay safe out there!
