I got into a head on collision with an SUV that came off two wheels while rounding a curve and crossed the yellow divider right into my little car. In that case it was definitely the height that did us in.
Sounds like a horrendous collision.
I will never forget the split second I recognized there was a huge mass of metal coming straight at me at a high speed and I resigned to the fact that it would probably mean life altering injuries. Good thing I wore my seat belt!
