As a motorcyclist who happens to wear Hi Viz in an attempt to stay alive I have to say the last thing I would ever do is pick a fight with 2 tonnes of metal and 57 air bags. On a bike I am at a serious disadvantage in both respects. Our man on the bike may have had a several screws loose but so have many car drivers who might just respond a lot more aggressively.
On a more serious note about lane discipline, there is one common circumstance where I don't pull into the nearside lane which observation suggests annoys some people. When in the middle lane, the lane markings to my left before and after an entry slip road change to close spaced white lines. I take this to mean stay in lane until the lane marking change back to wider spaced white lines. It's presumably dealing with the hazard of traffic joining the motorway. Anyone know if that is correct.
