You clearly have never suffered the Runcorn bridge at rush hour - one bus lane completely empty (except for aforesaid b*st**d taxis), only other lane backed up in a three mile queue - every day!!!!!!
Bus lanes are great big con. All they do is clog up every other lane, because nobody can get past the damn things driving at a steady 20mph and stopping every 100 yards, so everyone has to use the outside lane. And as for taxis.... :rant::rant::rant:
