I've often wondered if the millions thrown in to upgrade motorways from 3 to 4 or 4 to 5 lanes would be better used to upgrade the motorway police presence and educate/ persuade / [choose your own phrase ] those who cause the congestion by poor lane discipline .
Reduce the congestion =reduce the frustration = increase the road safety =safer roads .
I've always wondered about the benefits of having a second test to qualify for motorway status after holding a licence for a period .Personally ,I never see the need for it - I passed my test in the 60's in Glasgow .I learned to drive on S/C (single and double ) and D/C - and from my memories the same principles still hold true today ( and can be applied to motorways ) - I was taught to keep left unless there was parked vehicles in the left lane /I was turning right /or there was another reason .For about two years I played about on single track roads where the biggest danger in winter was a black faced sheep keeping warm in the road or in summer a tourist - equally dangerous IMHO

.There was also the added incentive to keep on the tarmac - no breakdown service in those days - so if you did come unstuck - carry a some rations ( and for breakdowns a good set of tools- sort of Mears in the Highlands)
Then lured by prospects I got the chance of a transfer to London ( my sister also getting a job in the civil service in London) and for six months we took regular trips home - about 600miles(each way) sharing the driving -never having had any motorway training -just good driver training .( And the knowledge that anyone causing problems would get put in their place by trafpol -highly unlikely we'd get fast enough to upset the motorway police in an old A40).
