"I know nobody agrees with me, but I don't see the point of this obsessive "lane discpline" thing. What happens is that you overtake, and pull over to the right (in France) and then you catch up to the car in front, and have to change lanes again. By this time, that lane is occupied so you either have to wait, or else (more likely) make a lane change into a space that is too small, creating a hazard. I'm not advocating tootling along getting in the way, but if you are generally travelling faster than cars in the slow lane, it makes sense (to me) to stay in the middle lane. If someone needs to pass you, he can use the fast lane.
OK – you can all hate me now"
And in one paragraph we have the reason every motorway in the UK is so awful regardless of size. I concede the continent's autoroutes are less busy, but every motorway in the UK, regardless of size is absolutely horrendous quiet or busy with a empty inside lanes and a 60mph procession in the outside.
As for lorries overatking each other at 56mph versus 55.8mph – don't even start me (also better controlled in France)!
