crazy enough, I watched an accident like this happen and the guy got up and walked away. He switched lanes at the last minute on I-264 in Norfolk. He cut right in front of an old lady driving a Toyota Camry. Dropped it, literally in front of her. I was going about 40 and in the next lane over, she slowed but rolled right over him. He rolled like a log under the car and popped out the back and sprang to his feet. Walked off to the side and sat down. He was scuffed up but nothing major. I pulled over to check him and wait for the paramedics. He was fine actually. The old lady thought she killed him. But, watching this happen, I think the fact that he was rolled over as opposed to being pinned under the car is exactly what saved him. He missed the tires completely. I say, try to roll over. Either way is going to be ugly, but I wouldn't risk having a body wedged under. Best to let the rebound effect happen.

 

What you're asking is do you drag him a 150 feet or 50 feet. Seems to me the answer is pretty obvious.

 

Just like my theory on kamikaze squirrels. Aim for the center and hope for the best.
