Earlier quoted context omitted.
IMHO, you're mis-stating the problem. One should take an uber/friend to the hospital if the ailment is not time-sensitive or in need of ongoing treatment so that the ambulances are freed up for more critical patients. Ambulances should have some level of cost associated with them to dissuade using them for minor ailments. Should that level of cost be thousands and thousands of dollars? Probably not.
Shouldn’t dispatch triage if you need an ambulance or not?
On the other hand, given that triage failures are rare -- cost/benfit wise it's probably better.
