Here is another point.
Air bags in the US are designed to stop a 200lb? man NOT wearing a seatbelt. As a result, the force of an air bag going off can cause injury to children and small adults.
In Australia where it is mandatory to wear seat belts and has been for 30 years, the force of the airbag is less than the US. As a result, there are few injuries to children because of airbag deployment.

I am also a believer in natural selection and not paying for other people's insurance. So I think the airbags should only deploy if the seatbelt is on, a funeral is much cheaper than rehab.
