A video captured by a cyclist of a confrontation with a driver, who trips and falls after giving chase, has gone viral.
The man, known only as 'uphillfreewheeler', posted the video to Youtube.
It has since had more than 4 million views.
The cyclist is filming in Reading when a car overtakes him. He calls out to the driver, saying "is that close enough"?
The cyclist continues to drive behind the driver, before a confrontation breaks out between the two.
At one point the driver tells the cyclist he was lucky he didn't hit him, as he was taking up the "whole road".
The driver then proceeds to park up at the road side, before getting out of his car and walking up to confront the cyclist.
He then reaches out his hand towards the camera, before asking the cyclist "would you like that broken"?
The driver then returns to his car. The cyclist follows him, saying "you've just committed an assault".
The driver begins to drive off but as the confrontation continues and the cyclist continues to film, he gets out of the car, saying "I'm taking your camera".
He then begins to chase the cyclist along the pavement.
Then, the driver loses his footing, sending him up in the air, crashing back down towards the pavement and then into a forward roll.
