There is nothing more infuriating then a driver who wants to get passed you even though you are going the same speed as the rest of the traffic. This driver was not only doing that she was also driving dangerously close to the cyclist and taking risks into oncoming traffic.
The rider in the video is using three cameras to record his ride, forward facing bike mount, rear facing bike mount and a helmet cam. In another upload GPS data is overlaid and it shows the cyclist is doing average 29mph during the incident.
When they approach the junction she finally sees her chance and overtakes the astonished rider narrowly avoiding a traffic island and cuts off the cyclist from going into the right lane.
