Awful, awful driver. 15mph permanently, stops for no reason, goes over speed humps at 2mph and has no perception of how wide the car is. Stops at gaps which are literally wide enough for two buses.
Dangerous on the motorway. Excessive speed passing other motorists, bullies his way past, flashing his lights, and tailgates in the most aggressive manner. Let him past, it's not worth your premium hike.
Give that guy a bog seat
