been there --- many yrs ago I had been working hrs like you and one day went home ill, got 15 miles from work blacked out, struck the concrete barrier in the center of the interstate, went back across four lanes of traffic struck the guardrail comming to a stop. didn't hit any other vehicles and a CHP officer was in the lead of the pack behind me. I woke up in an ambulance on the way to the hospital, the officer stated it took em 40 mins to get me out of the car. very little damage, the doors were locked :brows: other than a crumpled fender and two fractured vertibrae all was ok.
