Car drivers that doodle on motorway.They are oblivous of their actions.
Older drivers with powerefull engines that they never use.Most have newer cars.Spending the kids inheritance or doing Lorry Watch for a hobby.
I think seeing as we travel the most miles in a duty, we can encounter all kinds of things that annoy us, i personally have learned over the years to Just let them get on with it The situation described is annoying, the same as on a road like that, HGV drivers will saddle the 2 lanes to stop others getting past, the same with cars who use the hard shoulder in a traffic jam, and the HGV will block that route, and i cant get my head around that one, the drivers ( HGV again ) who expect everyone to pull over to the next lane on a motorway , as the slip road they are on is their priority, thats just a few examples.
Going back to the original thread, IF you were to squash the car driver coming up the outside, and there is a collision, the police will ask you Didnt you see him in your mirror if you say NO, then they will want to know why you never looked into your mnirror, when 2 lanes are merging into one, so the moral is, `You cannot win that argument, so best to learn how to chill, and not worry about losing 2 minutes of your time.
