There is a point , imo where at it becomes a courtesy thing. there is the school of thought where the queue is shorter if we use both lanes, and the school of thought where if we merge into one queue before the bottleneck then things dont jam up but keep moving, thereby causing less delay. The problem as always is people, pvr says its the difference between sheep and leaders, I think its a bit of both, In an ideal situation ,If we are sensible types, we know the time to merge safely and politely , but on one hand you get mr too nice guy getting into single file too early,so another load of nice guys follow suit, others carry on in lane two because they are way way ahead of the narrowing yet, they merge in plenty of time but nearer the bottleneck,all the time the queue in lane one is growing, leaving sometimes a mile or two of empty lane two. so that is a problem in itself as it is against the advice of the highway code and the drivers barrelling up lane two are not doing anthything wrong, in fact the greatest danger is the difference in speeds of the two lanes if a lane one driver decides he,s had enough of being oevrtaken and pulls out suddenly then it can result in a crash. back to the sensible merging point is where the courtesy thing arises, there are always drivers who are just thick or who dont care and just keep going in lane two just to pass that last car and try to bully their way in, annoying sensibly queuing drivers who then wont let them in, the whole thing escalates into at best a jam or at worst road rage. those that push right to the Very front are not Leaders, to my mind, but pushy or, rude or both and possibly plenty of other things too. as always its down to a bit of common sense, unfortunately not everyone has that :driving:
