This typical bmw driver overtook me literally right on top of a lane closure then slammed his brakes on almost ending up getting booted up the arse. We were diverted down towards yeovil and at the next roundabout he tried to squeeze down the outside of a fuel tanker who had split the lanes to make it easier. Finally, and while still within a 40mph zone, he pulled out to overtake the same fuel tanker directly into the path of another lorry. A driver with a serious deathwish going on!
