A lot can happen during a car accident. Between the initial shock from the impact, airbags going off and general disorientation, when you reach for your phone to call 911 you might not know where you are. Couple all that with cell phones' notoriously flaky ability at transmitting your exact location information to emergency service operators, and getting an ambulance to the scene of your accident can be incredibly difficult. To help sidestep that, Google has updated its Phone app to automatically display your location when making a 911 call.
