Example with concerns about when route context switches between network graphs and elevation inference

[uwtcat]

Hi.

Routing the following start and endpoints:
A: 34.055812, -118.251973
B: 34.055498, -118.251066

Yielded the following:

The path along the road network should switch back to the sidewalk network around Hill Street, because the sidewalk network does pick up at that point.
Also wondering about the switchbacks in the footpaths, but it is understandable that there would be odd artifacts that park footpaths might have.

A nearby issue:

Also- demonstrated in the second image: there are some significant problems with the inferred elevation for Los Angeles. there are multiple paths that are annotated as having incline 3e+1, or similar elevations, which will always render them inaccessible.
