I refer to your article (NCE 21 July) on fewer central white lines for many single carriageway roads. Be assured, the removal of central white lines and - I assume - stop line markings will save money, if not lives and injury.
My experience is that in Holland (where the idea has been introduced) most roads are fairly straight and often wider than in the UK with good sightlines where drivers and riders can adjust their road position and speed to suit other road users.
Infrastructure outside the older conurbations is to late 20th century standards.
Driver behaviour is also more consistent and, in my experience, more considerate.
However, in the UK, urban roads and their junctions are often restricted by building lines and the proliferation of street furniture and parked vehicles.
Rural dwellers such as myself could have great problems with the proposals on foggy nights and at bends where many drivers seem to think that 'racing' lines are the thing on right hand bends.
The proposals, if adopted across the three road types mentioned, sound like a simple and efficient catch all safety measure, when in fact the deadly devils are in the details of everyday use and abuse in many different locations and situations.
