Honestly, over the past few days, I've had several drivers drift to the right into my lane on dual carriageways or motorways just as I'm starting to approach and go past them. They just aren't looking in their mirrors, and most of them just seem to be half asleep and let their wheels drift across the lane line into mine before I have to honk them to tell them to gtfo back into theirs. Happened again today on the M11. I was in the slow lane and this car drifted into mine as I was starting to approach him (either accidentally or he wanted to get into my lane, not sure) before he realised and pulled back into his lane. As I went past and looked over to him he did actually put his hand up apologetically. But others I've honked and looked over to are just completely oblivious. Also, I'm amazed just how many drivers I decide to give way to on streets that simply drive past with no acnowledgement of thanks. So ignorant. Don't get me started on tailgating either, particularly white van man. All I can say is, they sure like to maintain their reputation.
