My sister in law gets into the middle lane for a 250 mile drive up the M1 and sits there for the whole journey at 70 MPH. When I asked her about why she does this she says she doesn’t like driving in the left lane because of the big Trucks and people in the right hand lane drive too fast. She also says “I am driving at 70 mph, which is the speed limit, so why would anyone need to overtake me” !!!!!!
I think the above logic applies to many people.
