> Google and Apple do some tricks based on WiFi to fix GPS in dense urban areas. Raw gps is basically unusable in these areas. Location Services doesn't just use raw GPS, no, but that's what most drivers (and passengers) are using. In any case, for several years, I only used the device GPS (instead of the full location services), and I never had any issues like what OP is describing.
