I really need to stop feedint the trolls. Lanes only get tagged if
they differ from the way to need it, the values of the way cascade to
the lanes. In any case when switching from 4 to 6 they should be split
already anyway.

Why do we need to use relations at all?

You are trying to push a square peg in a round hole rather than doing
it properly.
