OK, I'll wade in....
I usually travel on Motorways at around the speed limit, allowing for inaccuracies this means that the cruise is usually set to around 73.
If the left hand lane is clear I'm there.
When I approach a single slower moving vehicle I pass it and pull back in.
If the road is busy I usually stay in the middle lane.
During busy times, the inside lane is often full of lorries, the middle lane is often full of people driving right around the speed limit, and the outside lane is full of people going faster. There's a 50-60 lane, a 70ish lane and an 80+ lane. And that system works fine, everyone trundles along in a train and progress is good, if you want to change lanes, match the appropriate speed!
Even if there's a 1/4 mile gap in the lane 1 trucks I'm not going in there, firstly it's a waste of time because you'll be needing to pull back out in 20 seconds, 2nd, the car that was behind you will then be alongside and matching your speed so you're gonna get run up the back of the truck and will have to slow down, 3rd now that you've slowed down it's more difficult and dangerous to pull back out, the middle lane are all driving too close so there's no gaps and of course no one will let you out because that'll involve someone having to slow down or change lanes, which again upsets the status quo. So by the time you get back out you've braked and accelerated, it's cost you time and extra fuel and may have had a detrimental effect on your goal of a stress free journey

It's much, much better for everyone to maintain a constant speed, and if that means staying in the middle that's fine.
The problems come when lorry 1 decides to pass lorry 2 at 1 mph relative speed, then lane 2 is reduced from 70 to 55, and they have to pull into half a gap in lane 3 while trying to accelerate as hard as possible but the 95 mph Audi cock still has to brake, then the repmobile knobhead who's texting doesn't notice and ends up slamming the brakes on nearly causing a pileup and everyone gets aggressive, the status quo is ruined!
The only solution is more lanes on our motorways
I've always said that if you ever have to use your brakes on a motorway then someone, somewhere is driving like a knob
IMO this "crackdown" is once again bollocks.
Oh and I know what he means about the Pug drivers, we've all experienced the odd old codger in a Pug, but all marques have some preconceptions,
just look at Volvo
