WHILE TRAVELING IN A ROTARY OUR CAR WAS STRUCK VIOLENTLY BY A VEHICLE ON THE LEFT TRYING TO MAKE AN INCORRECT EXIT. THE IMPACT WAS HARD ENOUGH TO CAUSE THE ENGINE TO STOP OPERATING RESULTING IN A TOTAL LOSS OF STEERING LAND BRAKING. BECAUSE OF NO POWER, THE STEERING DID NOT RESPOND NOR DID THE BRAKES. THE DAMAGE TO THE CAR WAS PRIMARILY COSMETIC AND LITTLE MECHANICAL DAMAGE. THE AIRBAGS DID NOT DEPLOY AND IF THE CAR HAD REMAINED IN CONTROL IT COULD HAVE BEEN STOPPED BEFORE IT PROCEEDED INTO THE ONCOMING LAND CAUSING DAMAGE TO THIS VEHICLE AND THE ONE THAT WAS HIT. IF THERE IS SOME TYPE OF DEVICE TO TURN AN ENGINE OFF WHEN HIT WITH ALL OF OUR POWER STEERING AND BRAKES THIS IS A PROBLEM WHEN THE VEHICLE IS STILL OPERABLE.
