HIT A CAR THAT PULLED OUT IN FRONT OF ME AT ABOUT 20MPH AND THE AIRBAGS DID NOT DEPLOY AND THE SOS BUTTON DID NOT ACTIVATE. THEN I PUSHED IT MANUALLY AND IT FAILED TO MAKE A CALL UNTIL 20 MINS LATER AFTER THE POLICE ARRIVED. VEHICLE WAS IN MOTION IN THE CITY WHEN LOOKING AT SOME OTHER RANGE ROVERS AT THE COLLISION CENTER IT SEEMED LIKE THE AIRBAGS WERE NOT AS SENSITIVE AS THEY SHOULD BE.
