> but you make the choice
No US doctor would ever tell you how much any procedure would cost (even though they know, at least "in-network" doctors).
But if in your EMT you inform the patient of the potential costs of the ride, then yea, I agree they make an informed choice.
You’re getting in an ambulance, not calling a cab. You’re probably unconscious, maybe at least disoriented, overwhelmed, concerned about what’s happening more than doing math. Also you’re there on the floor bleeding, what’s your alternative? “Nah don’t worry, I’ll figure out this exposed fracture in the uber, I got points with them so it’s cheaper”?
I’d argue nobody getting into an ambulance is making an informed choice.
