Dealing with the M5 Southbound out of Bristol
There are four lanes going up hill after Gordano services. These taper to three at the top as the crawler lane for HGVs and caravan-towing cars are deemed to be over the worst of their hard slog.

No matter how fast you want to drive up there, so does everyone else so if you're in lane four (the inside lane) at the top you will be jammed into everyone in lane 3 (next one in) so you always have two lanes' worth of impatient speedy bastards suddenly having to mesh in the last 100 yards.

This is why you should always take Lane 2, avoid the juggernauts in the crawler lane but don't end up scrapping for a slot that is only 6 inches longer than your own car in between the aggressive angry drivers that are sparring it out in lanes 3 and 4. I've done that journey at least 75 times on busy Friday afternoons since there was a 4th lane built and seen plenty of mistaken comings-together at the top of that stretch because no-one is willing to give an inch and you usually end up sailing up the inside while they grind to a temporary halt. (p.s. this is not 'undertaking' as they're fucking things up by having to stop and the inner lanes aren't going to wait out of courtesy until they finally get themselves sorted again).

I'm having trouble interpreting this
Are you numbering the lanes from left to right as the driver looks at them? Because I would call lane 4 the outside lane, not the inside.

yes, left to right.
Left 1 = nearside to kerb, 4 = offside to armco (or concrete on that particular stretch). Did mongo do bad?

Dunno
I would call lane 4 the outside lane. WE CAN'T BOTH BE RIGHT! /gibbers

Lane 1 = nearside = inside = left-hand side of the road.
Lane 4/x = offside/farside/outside = closest to oncoming traffic.
