Morning folks, As the indicating thread threw up such a wide and entertaining varience of views I'd like to introduce a new conundrum. This was a discussion on the old Aol forums years ago following an unusual incident I was involved with on the M42. The traffic on the M42 was very dense and fast flowing resulting in the cars attempting to join the motorway to stop at the give way line before joining lane one. IE: The car decided he couldn't safely join the motorway traffic so he stopped ahead of a queue of accelerating cars on the slip road. There was no obvious cause for the unusual packing of vehicles on the motorway. There was no issue either on the M42 or hard shoulder, just a fast busy motorway and a queue of stopped cars on the slip. So, my question to the jury is this - If you were the first car to arrive at the Acceleration lane threshold expecting to find a safe gap to merge into and, knowing that there would be cars behind you doing exactly the same, what would you do?
