This dashcam footage from the United Kingdom shows a Ford Focus driver attempt to change lanes but end up having a nasty crash instead.

The clip, which was filmed near London, shows the camera-equipped vehicle in the outside lane. A blue second-generation Focus hatchback attempts to move across from the far lane but its driver seemingly fails to spot the camera car.

When the Ford driver eventually wakes up (likely thanks to the frenzied hooting), he or she loses control of the car, clipping the front of an Alfa Romeo Mito and crashing hard into the barrier.
