“I don’t need to wear a seat belt when I’m in the back…”

The risks of dying in the front seat during a car crash increase fivefold if passengers in the back refuse to wear seat belts. At 30 mph, a typical rear passenger is flung forward with a force of 3.5 tons at impact. That is enough to fatally crush the driver or front seat passenger. And the heavier the passenger, the more damage they can cause.
