What the F*CK were they thinking? The only reason motorways are the safest roads in the country is the relative speed between you and the other vehicles is marginal. Now imagine the relative speed between 0mph and the d*ckhead in lane 3 half a mile back doing 90mph+. That video needs to go to the police. The driver should be charged with dangerous driving.
Just a great driver, always alert and very safe. Your the best Alex Brooks!
