That's basically never going to happen. Emergency services in the US are already in a precarious position. And there will never be enough funding to increase coverage such that people out in rural areas can expect life-saving response all the time. Often people will die if you have to wait for an ambulance, and the only safe option is to drive the person to the hospital yourself, even if you're impaired.

(Then again, in the case of childbirth, it certainly could be safer in some cases to allow the birth to happen at home, rather than drive dangerously to a hospital a half hour away. Hard to say, and a spouse is usually not in a great position to evaluate the risk of staying at home.)
