Late reply but to specify, the crumple zones dissipating energy to protect the occupants, but in part the situation you’re describing airbags do a great job at preventing people from hitting the steering wheel / walls.

A very very advanced harness system might compensate a little for a lack of crumple zones during a very rapid deceleration collision. The issue isn’t so much as stopping someone from but being thrown around in the car, seat belts do that, but nothing can stop one’s internal organs from doing the same thing inside their body. So when a body stops during a rapid deceleration, internal organs still try to move. This movement tears everything, most notably one’s aorta and a torn aorta means death with no possible chance of survival.

A small tear in one’s aorta and one may survive long enough for emergency services to show up, a bad one and they will have bleed out before a 911 call taker has time to answer a call for help.

Late but USA, wanted to share a personal experience. While at work I collapsed and had to take an ambulance to the hospital. I got sent the bills for everything. Including the ambulance ride. I stayed in the hospital overnight for observation. They couldn’t figure out what happened and I didn’t have symptoms anymore so I was discharged. Whole event cost maybe $500.

Here’s the kicker, I work(ed) as a paramedic for the ambulance company that transported me. I had insurance that was not from the company so prices were reasonable relative to what one would expect in the country. Had I been insured through work, well, the insurance provided by the company doesn’t cover transport by that company’s ambulance.
