Shocking footage of a car and motorcycle racing each other along a narrow country road was filmed by a stunned motorist.

The video, which was taken from a dashcam, shows a sports car attempting to go past the motorbike at high speed while travelling in the right hand lane.

The driver who filmed the video said "the car is clearly racing the bike".

She said: "By the time I turned they were almost at the bend in the top of the road.

"There's some pretty scary speeding going on between the car and the motorbike that are racing there - thankfully that part of the road is fairly long and straight.

"Sadly no registration plates gained on this video - but I doubt the camera would have caught them even if I'd been first in the queue they were moving that fast."

The incident happened on Sunday evening on Missenden Road, which links Great Missenden to Stoke Mandeville via Butler's Cross. The car taking the footage was attempting to turn out of Hampden Road.
