I would prefer to live in a world where all the cars are small. Taking your example of a corner clip, the larger car would fare better; the smaller car will spin more. There is no better description than "arms race." I understand there are edge cases with rollover, etc. but the first rule is mass. I suppose the second rule is where between the two cars the force is absorbed. Ideally bumper-to-bumper. Modified lifted trucks ought to be banned as far as I'm concerned; it defeats the factory design that had to comply with laws.
