It sounds simple, but the main goal of an airbag is to slow you down at a safe, survivable rate. Without one, your body slams into the steering wheel or dashboard at the same speed you were driving. That’s like falling off a three-story building. Ouch.
Think of it as a velvet-covered brick wall versus a crash pad. The wall stops you instantly, which is brutal. The airbag is the crash pad that extends the stopping time, so your brain and bones don’t go splat.
It’s all about physics—making a sudden stop feel a little more like a gentle, rushed hug. Pretty cool, right?
