If I was the “patient inside” the ambulance, I’d be asking WTF?
I’d be saying: “Whew!”.
Depends on why the patient was in the ambulance. If it was just a “transport” to rehab or something that was not an emergency, the Paramedics have a “duty to act.”
This situation presents itself more than people might realize. My daughter is a paramedic...and this was a “couple of times a year” type of thing. Not dramatic car flying, but coming across an accident.
Dash Cams allow us to see more of this stuff than we ever have before.
