This is awesome. Would definitely download a local higher-res version if that were an option, maybe using Google Street View data? Also, if this was a live MMO, that would be fun. Not that there's really a game aspect here other than the coins when driving a vehicle, but anything to give some life to the sim SF city would be nice.

Seemingly lower-hanging fruit options I'd like to see:

- show street names, maybe some landmarks or businesses, togglable

- enter address to teleport to

- enter address to get directions to, GPS style, to travel there manually

- get coordinates / current location as a URL to share

- zoom in on minimap, or expand minimap, so that teleporting can be more precise

- changeable avatar

- more dynamic weather / lighting options
