Lexus is300 2002 vehicle rollover on freeway. defect that caused the car to roll was from the left front wheel/rim broke in half while driving. i was merging and heard something break under the car. my steering wheel turned a hard right forceful and without my control. i tried to straighten the steering wheel out from this involuntary harsh direction of vehicle, it was locked up. i turned completely around facing traffic. all attempts to turn the steering column would not allow me to do so (completely locked position). the vehicle spun and i heard and felt the back end hit something. the car catapulted over a 8 ft. fence that separates the access road. the car landed on its roof. my airbags never deployed! impact crushed the roof into the ground i was suspended upside down by my seat belt. the car engine was still running. i attempted to unlatch my seat belt, it took a few attempts. i could not find a door handle, or window to get out. i tried forcing the drivers door open. it would not move, i was trapped inside the upside down vehicle. in a panic, i feared the car would spill gasoline and catch fire. i turned the ignition off. i then realized no one stopped to help...i forced my body to hit the door over and over, to break it open. i got the side mirror to break allowing the door to open a few inches...just enough to crawl out. i went back in to find my phone and call 911. at that time a person pulled over. i found my phone and for some reason i decided to take a picture of the vehicle. i captured the broken wheel in the picture. police asked me what happened, i said over and over "it locked up"...my phone battery died right after i took the picture. i didn't have medical coverage for emergency, so i didn't go to the hospital. the cop said, "people don't walk away from this kind of accident" he advised i go with the ambulance, however i couldn't afford the cost. i didn't realize i was injured, until later. no one has ever seen a wheel do that. *tr
