Automotive safety gear is rarely designed to protect your genitals from the impact of a crash that could reduce them to a pulpy, useless mass of bloody tissue. So we should be grateful that the designers at Hyundai are looking after our interests. But its newly patented crotch-level airbag isn't designed specifically to protect our nether regions.
Carbuzz explains that a common problem in car crashes is that people wear their seat belts too high. They're supposed to rest low upon our hips so that the impact of a crash is absorbed by the pelvis. If the belt is too high, a human body in motion tends to slip down or "submarine", driving the seat belt into the belly.
This new airbag deploys at crotch-level to prevent this downward motion, keeping the seat belt at pelvic level.
