In truth, I guess as I do on a few interesting back roads, with no oncoming traffic... I would generally take the straightest line, unless really in the mood to get my knee down or more likely these days the least line of resistance relative to minimising skeletal pressures and muscular effort into the my old Trad Mogs steering system..... Which line would you honestly take.

In the UK of course, double white lines should never be crossed, unless the road is obstructed...
