I WAS DRIVING ON THE EXPRESS WAY A MOTORCYCLE AHEAD OF ME APPLIED HIS BRAKES I FOLLOWED SUIT. THE 350Z ROADSTER BEGAN TO SWERVE AND SPIN UNCONTROLLABLY AND STOPPED AFTER I HIT THE SID RAIL RESULTING IN MOTORCYCLIST AND MYSELF GOING TO HOSPITAL THE ISSUES WITH THE TIRES ON THE 350Z ARE WELL KNOWN BY CONSUMERS, NISSAN, AND THEIR DEALERSHIPS. I HAVE TAKEN THE CAR ON AT LEAST THREE OCCASIONS TO THE DEALERSHIP FOR EXAMINATION AND POSSIBLE REPAIRS BUT THE TIRE DEFECT AND HANDLING REMAIN. THIS IS UNFORTUNATE SINCE THEY HAVE TRIED TO UNSUCCESFULLY FIX THE ISSUE ON OTHER MODEL YEARS OF THIS VEHICLE
