Motorway driving. Things CHANGE every 3 seconds! 

Moving over to allow joining traffic to use lane 1 is very kind, but sometimes not possible. When such occurs it is required that the joining traffic moderates speed and merges into existing traffic, so often one feels joining traffic expects whoever is in lane 1 to make space, even if this means slowing down. That is wrong. Sometimes I feel as if joining traffic is "barging in" expecting all else to take avoiding action, such drivers don't have sight of upcomign traffic either through circumstance or because they are not looking (interested to look). More driver training is required for this aspect of dual carriageway and motorway driving.
