I worked with a USN heli pilot & commander. They had to go repeated tests where they were strapped into a helicopter body, blindfolded, and then it was dropped and inverted into a pool. They had safety divers immediately in the water, but to pass, they needed to get unstrapped, find their way out of the vehicle, and to the surface.

From amateur auto racing, I also know that harness and latch design is critical to being able to escape in an emergency. Again, we practice getting out of the vehicle quickly.

A video is just not even close to what would actually help the passengers. Note that the pilot escaped ok, but no passengers did. Might as well just take their money and say "good luck".
