I would say there are times that it is really not possible to pull over to let traffic pass.
Why endanger yourself if the nearside verge of the road has broken tarmac/potholes/debris/wet leaves/raised ironworks, just so that someone can cut a few seconds off their journey time.
Also the camber of the road may not let you take a nearside road position either.
In anycase the guy needs banging up in jail for a long time and a lifetime driving ban.
Could the guy filming in the car behind, if he was filming the guy driving for some home movie ego boost, be brought to account as an accomplice for dangerous driving?
Just a thought.
