Theres absolutely no common sense on the motorway however you look at it though, like the hatchback at 90mph brigade that seem to think you have to violently swerve in and out of the lanes between the smallest of gaps in a bid to overtake, half the time not even bothering to indicate, all instead of just sitting comfortably in the middle/outside lane until there is a reasonable enough gap to warrant moving back in. Its common sense.
People being forced to constantly brake is what spoils the movement of motorway traffic. That and lorries overtaking
