Horrifying footage of a cyclist's collision with a car as it pulls into his path has been posted online.
The video - simply entitled 'WTF.' - shows an unidentified man riding along a designated cycle path in Clapham Road, London.
The car in question can be seen pulling up to the junction before advancing right into the path of the cyclist who hits him at speed.
He shouts something before hitting the side of the vehicle and coming to a jarring halt, screaming in pain as he sits on the road.
The incident happened on 20 May but was uploaded to YouTube on Monday with the caption: "Ok, guys here it is. On the 20th May 2014, I was riding my new bike to work testing it out before my trip to Malaysia to ride kuantan 160."
