The issue here is that we as a society recognize different standards of consent. In the framework of Medical Consent, if someone is unconscious, then they are implicitly consenting to medical treatment[1][2]. I don't have any background in contract law besides occasionally reading /r/legaladvice, but it seems unlikely that that matches our common-law concept of consent to a contract. So where does that obligation to pay for the ambulance come from? It doesn't exist in the UK, but did it before 1948? Are there statutes in US states which create that obligation?
