Gun enthusiasts often protest: Cars kill about as many people as guns, and we don’t ban them! No, but automobiles are actually a model for the public health approach I’m suggesting.

We don’t ban cars, but we work hard to regulate them — and limit access to them — so as to reduce the death toll they cause. This has been spectacularly successful, reducing the death rate per 100 million miles driven by 95 percent since 1921.

It is pretty clear how to do it. It is just a matter of public will to get it accomplished.
