@johndoh couldnt disagree more. (warning anecdotal evidence coming…)
I haven’t had to for a while, obvious reasons, but I drive a lot for work/union meetings all over the country. I drive a Transit, so not the fastest vehicle in the world, but on motorways limit is the same as everyone else. I have barely left the county (Devon) before I lose track of the number of vehicles that do this, in this order, every. damn. time.
1.Quite happily stay behind me in the left lane
2. Pull out to over take as I do
3. Sit as close to my rear bumper as they can even though the right hand lane is empty
4. Once I’ve moved back left, stay in the middle lane
5. Decide they want to pass me and do so by speeding up
6. Pull back left and SLOW DOWN meaning I either have to slow down too, or over take.
7. 5 miles down the motorway, go back to step 1 and repeat.
Moral of the story? (Some of? A lot of?) Drivers want to overtake any and all traffic in front of them, whether they “need” to or not.
