I WAS ACCELERATING TO MERGE ONTO A FREEWAY. WHILE I WAS LOOKING IN MY MIRROR, THE CAR IN FRONT OF ME STOPPED. I HIT HER WITHOUT EVER HITTING MY BRAKES. I WAS GOING APPROXIMATELY 30-40 MPH. THE PASSENGER SIDE AIRBAG DEPLOYED AND BOTH SEAT BELTS LOCKED. THE DRIVER'S SIDE AIRBAG DID NOT DEPLOY. THE FAULTY AIRBAG WAS REPLACED BY MY INSURANCE COMPANY, BUT SO FAR, HONDA HAS NOT EXAMINED MY CAR OR THE AIRBAG TO SEE WHAT THE PROBLEM WAS. *NM
