Unless a high speed crash. In the Princess Di tragedy, the only survivor was the front passenger who was the only one belted and the airbag saved his life. Here's what happens without the bag while belted. High speed is considered 35MPH and above
Note this is a belted dummy on a modern car unlike below. Things have not changed much in 35 years with belts alone.
One more. Just watch the first 1:40 of this
video. The famous "built like a tank" Mercedes with a belted dummy slams the steering wheel at 35 MPH. without an airbag.
Exact same MB 123 with an airbag. Note at 20 sec, the passenger seatbelt pretensioner prevents the passenger from hitting the dashboard but the driver must be saved by the bag because the steering wheel is right in his face. These are at 35 MPH, heaven help you at 40+ MPH. Airbags may cause some injuries no doubt but I'll take a bag over a steering wheel any day. These are not fluke tests. The 123 in the video was not marketed with an airbag. The 124 300E was the first midsize MB with an airbag in 1986, I owned an '87 in 1992.
Scary 1980 Tercel crash test no airbags, MB was better but still not face friendly without the bag.
Airbags save lives. 25-30 years ago, airbags blew out at up to 200 MPH at low speed and did a lot of damage. Todays smart bags are far better but still can do damage. Ever feel an airbag with your fingers? Its like burlap made from nylon. Very abrasive and not skin friendly. I have interviewed dozens of people who have had airbags hit them in the face and every one is glad they had the bag vs slamming their face into a steering wheel (even while belted, you'd think the belt would be enough but it's not.
In 1996, Congress had hearings on airbags after another child was decapitated in the passenger seat of a Jetta in Utah. Then Sen. Dirk Kempthorn was the only one on the committee who understood the issue and the idiot head of NHTSA Ricardo Martinez proved himself to be truly incapable if heading NHTSA.
