the former creates a higher deacceleration (assuming collision time is equal) since acceleration is the rate of change of velocity for both the car and the occupant, assuming of course they are wearing a seat belt.

Claiming "excess" momentum is converted into deacceleration is nonsense. Momentum is not converted into other quantities, it is conserved/transferred shared amongst other bodies in the collision.
Actually sudzy, I think I've just realised exactly where the flaw in your argument is - it's the assumption that collision time is equal. The car can't just travel in the opposite direction instantaneously. At some point its travelling 1km/hr, then 2km/hr etc up to the point of 10km/hr in the opposite direction (as per your example). This can't happen in zero time.

If you dispute this as well, them please PM me and we'll continue the debate in private.
