I run an old diesel. Lovely fuel economy at 68mph roughly so I tend to stick there, rather than waste fuel. Obviously I speed up or slow in response to a need and drive sensibly, but I’m relaxed and will potter along. If the roads busy I do keep to the speed of the road, Im not awkward.
However, even on an empty motorway with even 3 empty lanes to my right some people insist on driving up behind me at around 80mph, then braking and tailgating. Even flashing their lights. I don’t move faster, I point to the lovely empty lane to my right.
No one else in sight, it still happened repeatedly to me the other day.
What is the logic? Why? I drive back through France, and it only started after Dover (I think the road was so empty as Dover was gridlocked! No escape)
