I wonder if it uses Significant Location Change monitoring—which apparently works around “Always Allow” location permissions, and would be consistent with allowing location “once” or “while using the app” (which Lyft, I believe, requires as part of delivering its actual service). It also might explain why only SFO: is SFO one of your Apple-determined-and-enumerated “Significant Locations”?
(Edit: annoyingly, the parentheses are part of the URL. I don’t know how to encode them to make HN’s link parser happy, so you may have to add them by hand if you follow the link.)
