There’s degrees of “conquered”. Seat belts ‘conquered’ motor vehicle trauma before airbags did. Each new thing helps fill in the gaps left by the already-existing things.

I question your example

While airbags functioning properly with a properly sized adult reduce trauma, that's a lot of conditionals.

Seat belts conquered ejection and death, but people still didn't wear them, so active restraint and airbags became policy to have at least their 13% chance of being effective.

Seatbelts reduced the death toll dramatically compared with no seatbelts. Airbags and seatbelts together reduce the death toll dramatically compared with just seatbelts.

In most of the world it's considered suicidal not to wear a seatbelt while in a moving vehicle.

And unfortunately the US took the stance that airbag design should take into account that a seat belt will not be worn. US airbags explode with much more force and cause many more injuries than European ones.
