TOO IMPORTANT NOT TO SHARE
Mercedes Benz was the company who first produced a car body design that absorbed the force of a collision on impact. One Mercedes Benz TV commercial shows their car colliding with a cement wall during a safety test. Since then of course many other car companies have followed its design.
Someone then asks the company spokesman, "Why they do not enforce their patent on the Mercedes Benz energy-absorbing car body?"
He replies mater-of-factly, "Because some things in life are too important not to share."
