Largely true, but it's crazy what the difference of just a few feet of slowing down does (rather than zero feet of abrupt stopping) to acceleration forces. The crumple zone on a car only has to be 3 feet long to turn a 60mph crash from a fatality to a horrific injury.

    Check out the absorption barriers on the edges of racetracks. They’re remarkably small for cars that could be hitting them at 100+ mph.

    Of course, the cars themselves are also designed to save the driver but it’s the same concept.
