Ive never understood the logic of everybody cramming into the inside lane and leaving the two outside lanes empty. Does anyone really think constantly swapping lanes as they overtake again from the overcrowded inside lane makes any sense? Happily instead most people recognise they should pick the lane according to what speed they want to travel - around 60mph for the inside, 70mph for middle and 80+ for the outside, giving way to anyone who wants to go faster.
