125mph YouTube video prank

A video clip that appears to show a driver filming himself tearing down a motorway at 125mph is being examined by police.

The footage, posted on the YouTube website, shows other motorists swerving to desperately avoid the man's car, which is being driven at almost double the speed limit.

The clip has since been taken down.
