 There's a multifaceted problem here. We're trying to please everyone,
which won't happen, but by not doing something, we're still not pleasing
everyone. There has to be some give and take between all of the uses for
OSM. Changing PA to a trunk may work for vehicle routing purposes, but it
may not work for bicycle routing purposes.

Is there a better suited system?
