If a way connects to an area that represents a connecting road, then 
there is presumably a simple rule based on the 'rule of the road', i.e., 
drive on the left (right) according to the rules of the country in which 
the roads are situated. In other words, if approaching from the left on 
the following diagram, the only course possible (in the UK) is to branch 
left at the first node, and proceed in a clockwise direction with 
respect to the area:

    /              \
--o                o--

I've only considered this simplest of scenarios - doubtless there are 
more complex situations where this rule might 'break'?
