Thanks for the reply.

On the "two identical vehicles head-on = one vehicle into an immovable
wall" thing, it seems self-evident that you could also extend that
analogy and say that a heavier vehicle and a lighter vehicle head-on
would be equivalent to the lighter vehicle hitting a wall that is moving
at some advancing speed (i.e., more damage than head-on into a
same-weight vehicle), and the heavier vehicle hitting a wall that is
receding at some speed (i.e., less damage than head-on into a
same-weight vehicle)

Only helps you if you collide with another vehicle. Does exactly squat
when you hit something immovable, or significantly larger than you (like
a semi)

I'll take my cars light and nimble, thanks, so I don't wreck at all.
