Riders and drivers are also not local. I travel a lot and yet my star rating, profile picture and payment details work regardless of if I'm in the Bay Area, Berlin or DC. Further I've heard of Uber drivers giving rides to other regions, e.g. SFO airport to Sacramento (apparently fairly common as the Sacramento airport has limited service and is expensive).
