They did, and do. Mercedes invented, and patented the crumple zone, but choose not to enforce the patent. Huh? They decided that enforcing patents on safety devices would be detrimental to the driving public, and so they allowed any and all other car manufacturers to "steal" the technology.
This is one case of where Mercedes had the foresight and conscience to put people ahead of profits.
