If your condition isn't time sensitive and your life is not in danger, then there is really no point calling an ambulance. 

The purpose of the ambulance is to get someone in critical condition to the hospital because their health is time-sensitive.

A broken foot is going to heal just fine with treatment whether you get to the hospital in 20 minutes, 1 hour, or even 24hrs.

I slipped on ice and broke my arm when I was a kid and we weren't sure whether it was broken until the next day when it still hurt.

Drove to the hospital, got a cast, and it healed just fine.

Yes ambulances should be less expensive but taking an ambulance for a minor injury is just dumb and robs resources from those critical patients that actually need emergency transport.

Lol people will call for abdominal pain that's "100/10!!!!!" even after you specify to them that 10/10 would be the equivalent of you're literally on fire, the worst pain you've ever felt in your life, etc, and they'll be sitting there on their phone texting with a 115/68 BP and 65 hr and demand dilaudid. I swear it's the same people on reddit saying they'd never "call the wee-yoo wagon" and then complaining that we took a whole 5 minutes to get there.
