I don't like the idea of shelling out a ton of money to repair a banged up car, but it's more appealing that trying to shell out for a banged up human.
Despite the Automotive Marketing, it's not an Either/Or situation. Neither does me questioning ridiculous bumper repair costs make me anti-safety.
If you read what I linked from the IIHS (who have a major interest, including fiscally, in minimizing human damage), you'll understand how the older bumpers I'm talking about actually performed better than current ones.
I've seen plenty of bumpers apart on modern cars. Aside from a minor sensor or 2 not present on older cars, all they really are is a plastic skin over a big chunk of styrofoam, backed by a small metal horizontal bar - typically solidly mounted. Plastic skin goes on with quick-attach plastic clips, and maybe a (very) few screws - all of the design is optimized for manufacturing speed, and minimal material cost/weight. Much of the increased repair cost today is simply from the fact that these modern bumpers are one-time-use throwaway systems, after just one low-speed impact.
