It's all to do with relative velocities but I won't go into the details. Those who don't believe me yet won't be swayed by a proof either. Obviously I can't speak for the effects of crumple zones and glancing collisions etc but to answer the physics part of the question, definitely aim for the wall rather than the car.
Yep, i believe you, as i said back on page 1....
