Really? Because I've always tried to keep ways relatively short for a number
of reasons, and if there's no suitable junction around I'll just arbitrarily
start a new way. This means:
a) Names show up on maps at regular intervals, so you don't have to follow a
road away 5km from the place you're looking at to find out its name. This
could of course be fixed in any renderer.
b) When someone else downloads the area with a bit of the way in it, they
don't have to keep following it for 5km downloading new chunks of data before
they can modify it.
Is that good/bad practice?
