>"Sure, but roads are added/expanded far faster than bike lanes, so the percentage of roads that have bike lanes has been going down over time." I don't believe this statement is true at all. How do you expand or add to a street in the city? A street is bounded by sidewalks and/or building frontage that is private property. There is finite amount of space often laid out in a grid. It is also quite a rare occurrence for a new street to be added to a city. The only circumstances I can see that happening would be as part of a major redevelopment project.
