I just added some max_speed= tags for #OpenStreetMap in Bloomington, Indiana.
Our city code has a default speed limit 25 mph. Exceptions are published in a table in the city code.
It seems possible that adding the correct lower-than-default speed limits from city code to OpenStreetMap could reduce the likelihood that routing algorithms would route car traffic there, which could in turn keep the street safer for other road users.

@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.
