@markstos@pleaseclap@bloomington_in yeah, I think when the state database was imported many years ago it included the at the time correct speed limits for streets, though most of them were unsigned. Then a couple of years ago the city reduced most streets with signs to be safer, but no one got around to fixing OSM.
@markstos@pleaseclap@bloomington_in last year a group of us we confused why Cambridge was so poorly rated on the People For Bikes city ratings and realized that the city changed most street's speed limits. After going through and fixing them in OSM, this year Cambridge jumped up significantly to be rated much closer to what I'd expect.
@markstos@pleaseclap@bloomington_in without knowing the local area, I was thinking not that there might be basically parallel routes with different speed limits, and car routing would choose the higher limit option, while bike routing chooses the lower limit option. But with the assumption that the limits reflect something else about the road condition and how comfortable biking is, the routing algorithm now has a better signal to choose the better route

@markstos @bloomington_in on the other side, bike routing likely gets better too
