As someone who travels everyday between junctions 19 and 20 of the M4 Motorway this is scary.

A driver who did a u-turn at the toll booths of the old Severn Bridge, drove several miles on the wrong carriageway before crashing into a motorcyclist.

The 73-year-old took his white Skoda Fabia back along the M48 and onto the M4 where the collision happened between junctions 19 and 20 near Bristol.

Christ that could have been me.
