seems like a very similar idea to a site made by walzr, previously posted to HN. i’ll find the link somewhere

It was this one: https://walzr.com/sf-parking/

>This site only worked for 4 hours until the SFMTA cut the data source I was using. This data is a snapshot of how it looked on Sept. 25, 2025 at noon.

What a shame! Still such a cool idea!
