In a CBS This Morning segment, engineer Jack Jensen revealed how General Motors is making crash test dummies (also known as "anthropomorphic test devices" or ATDs) much more high-tech and realistic, ultimately resulting in safer vehicles on the road.

Within the lab, Jensen and his team build, crash and re-build these high-tech ATDs, studying the effects car accidents have on parts of the human body, in the hope that the learnings can save lives in the future.

These techniques are a far cry from the crash tests of old. The CBS video shows how engineers used to roll cars down steep hills to simulate roll-overs and would actually drive a car and jump out at the last second for a head-on collision test.

Check out the video for yourself above to see how today's cars are using eerily lifelike dummies to ensure your cars are as safe as possible.
