Car headlights are aligned to point slightly towards the nearside to
avoid dazzling oncoming drivers. For instance when we take our UK cars
to mainland Europe, we have to 'convert' the headlights to point the
other way,

If there is no physical barrier, I would expect dazzling to be a major
problem on that stretch of road.
