Some people thinks that teaching the public how to use air bags is the government's responsibility. The government can help you to teach people the right way of using air bags. But the big part of this responsibility relies on manufacturers. They are the ones who produce and test these bags, so they know the most efficient way of using it.
Manufacturers can teach people to use air bags in a lot of methods.
Providing each consumer with a small booklet, that shows how an air bag works and how to use it is a useful way.

For sure, all of these methods will help in decreasing the rate of air bag accidents. In the time being, people know a lot about cars, but when it comes to air bags, they know nothing about them. Definitely you realize how serious and dangerous is this problem, you know how many people have been killed through the recent years by air bags.
