We were driving back from a trip, both of us very tired, and we had decided to alternate driving, me starting first. Well turns out I wasn't as capable of staying alert and awake as I thought I was, and I fell asleep at the wheel. Needless to say, the car ended up flying off the side of the highway into the woods hitting a few trees completely totaling the car. I know I made a stupid mistake, but now I know better never to DWT (drive while tired). What I want to know now is, since I was driving my friend's car, how will this work with the insurance company? Will my insurance or his insurance cover it, or neither?
