ON, 6/17/12, MY DAUGHTER AND I WERE DRIVING EAST BOUND I-96 AND INVOLVED IN A NON-FATAL INJURY ACCIDENT BTWN BEECH DALY & INKSTER. THE ACCIDENT STARTED IN THE FAR RIGHT LANE AND ENDED WITH SUV FACING OPPOSITE DIRECTION OF TRAFFIC, LEFT LANE OF HWY. I HIT A POTHOLE, APPROXIMATE DIAMETER OF A YARD STICK, FILLED WITH WATER AND IT SEEMS LIKE I LOST CONTROL OF THE STEERING; ALMOST AS IF THE VEHICLE HAD INSTANTLY SHUT DOWN. THE VEHICLE EASILY COMPLETED AT LEAST A 360 SPIN OUT. WE WERE ABLE TO WALK AWAY WITH MINIMAL INJURIES DUE TO CLIPPING ANOTHER SUV TAIL END INSTANTLY BEFORE GOING STRAIGHT INTO THE CEMENT HIGHWAY DIVIDER! I DIDN'T REALIZE HOW MUCH MUSCLE STRENGTHENING WOULD BE INVOLVED IN MINE AND MY DAUGHTERS' HEALING PROCESS. I HAVE BEEN IN TO SEE AN INTERNIST, NEUROLOGICAL SURGEON, PHYSICAL THERAPIST, OCCUPATIONAL THERAPIST, MASSAGE THERAPIST, NOT TO MENTION ALL OF THE CAT SCANS, MRIS, ETC. PERFORMED AT MULTIPLE HOSPITAL LOCATIONS. MY VEHICLE INSURANCE CARRIER WAS NOTIFIED OF MY HEALTH INSURANCE RESTRICTIONS PRIOR TO SIGNING WITH THEM AND PRIOR TO THE MVI. THE REDFORD, MI POLICE REPORT INDICATES NO INJURIES BECAUSE NEITHER MYSELF NOR MY DAUGHTER WERE TAKEN AWAY BY AMBULANCE SINCE THE INJURIES WERE NOT LIFE THREATENING AND WE WERE BOTH IN FORMAL ATTIRE, BOTH BRIDAL PARTY MEMBERS. THE VEHICLE WAS TOWED AND TOTALED BY INSURANCE, LOAN PAID IN FULL; HOWEVER, APPARENTLY CONCERNS HAVE AROSE TO, PERHAPS, TO THE EXTENT OF OUR INJURIES SO NO MEDICAL PROCEDURES HAVE NOT BEEN PAID TO ANY OF THE SERVICE PROVIDERS, AS OF TODAY'S DATE (11/15/14). MY DAUGHTER AND I WERE PICKED UP BY ANOTHER GUEST ATTENDEE SO WE WEREN'T HOLDING UP PROGRESS, BEING IN THE WEDDING PARTY AND CARRYING ALL DECOR FOR AFTERWARD FESTIVITIES. NONE OF THE VEHICLE AIR BAGS DEPLOYED AND WE WERE GOING 60-65MPH (FRONT, SIDE, REAR, NO WHERE)! THANK YOU, GM, MDOT AND CURRENT EMPLOYEES FOR STAYING TRUE TO USA & MI! *TR
