We need an open version (as OpenStreetMap is to Google Maps).
Mapillary (https://www.mapillary.com/) has surprisingly good coverage in some places, but the experience is lacking, partly because most of the images (where I've looked) aren't 360 views.
Panoramax[0] is another, perhaps more open option, though it is currently primarily used in Europe.

Is this actually open source? The few datasets I found on there are under non-commercial licenses.
Mapillary is of course owned by Meta these days.
