Diminish motorways except where they touch streets

[Nate-Wessel]

I had this crudely implemented before, but now it is not being handled.

I want to keep motorways and on-ramps on the map for context, but I don't want them to dominate visually or maintain continuity when seen from a distance. I.e. this is bad:

My thought was that their color could fade out as distance increases from a point of connection with the street network. I had some trouble implementing this in pure SQL with recursion.

I've begun to implement this with the help of pgRouting, but it's a been a bit difficult to set rules for what counts as a point of contact with the street network.

Does a crosswalk/sidewalk count? Does a limited access "secondary" road count?

[Nate-Wessel]

I may actually want to expand "motorway" as a classification to include un-bikeable major roads.

There are some problems with this still, but it is starting to look a lot better!
