@DemonHusky @markstos @bloomington_in Bike routes will get more direct, but "better" may not be applicable, since the more direct routes also encourage drivers to speed
That said cities tend to add bike lanes only after people get annoyed with bike traffic, so maybe down the road it might add some lane miles
@pleaseclap @DemonHusky @bloomington_in I can’t see how any routes will become more direct for anyone, because no new more direct paths are being added.
Tagging a slow speed limit is a signal that cars may want to take a less direct route on streets with faster speed limits, while tagging a high speed limit is a signal for bike routing that cyclists may be less safe and may themselves prefer a less direct but safer route.

What DemonHusky said:
A map app suggesting a route for a bike will try to minimize time via the slowest streets. For a car, it will try to minimize time via the fastest streets (which are usually more direct in terms of distance)
So if the algorithm suggesting a route thinks all streets are the same speed, bikes and cars will be suggested the same low-distance routes, which will usually be routes featuring excessive speeding by drivers
@markstos @DemonHusky @bloomington_in
Besides speed, there's probably also an "is there a bike lane" check, which would mitigate the problem a bit in places where the main roads mostly also have bike lanes
@pleaseclap @DemonHusky @bloomington_in That’s right. Many signals are involved. Some factor in cyclist aversion to hills for example.
