Yeah, so almost everyone.
> Driving is one of the most dangerous things humans do. The argument that all health care should be private– the perspective this comment addressed– would not make such a consolation simply because it's common.
Car deaths are about 1% of deaths. Heart disease and cancer are each around 15x as likely.
Even if it's high on the danger scale, I don't think it would be a very big factor in health care costs.
