When there is a junction of two highways that are both mapped as two
parallel oneways, the "via" of turn restrictions will not be a node but
one of the four two-node lines (an edge of the "square") at the
crossing.

As far as I understand, mkgmap currently ignores turn restrictions where
the via member is not a node. My guess is that obeying turn restrictions
could decrease the maximal routing distance, not increase it.
