I tried to get into OSM a few years ago, and the barrier to entry seemed a bit high. Maybe I'll try again. For all I know, the lanes are properly marked, it's just a routing issue. In Israel, the bus lanes are a bit odd. A lane can be a turn-only lane for cars and straight-only for busses. So, it's a bit complicated. Even Google Maps can't handle it.
this can definitely be mapped in OSM. as far as a high barrier to entry, I'd say that there is a low barrier to mere entry. StreetComplete provides extremely easy OSM editing. Unfortunately, dong something complicated like mapping the turn lanes and what bus restrictions exist on turn lanes is not easy
Thanks for sharing StreetComplete. I hadn't seen that. My interests are usually around K8s, Linux, containerization, IoC, etc, so I honestly hadn't looked as deeply into OSM recently as I should. This looks like a fun way to contribute back a bit.
