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.

Auto safety has shown a very consitent rate of improvement with deaths per passenger mile halving about every 20 years, since 1920.

That's the red line in this chart: https://upload.wikimedia.org/wikipedia/commons/thumb/4/4f/US...

The period of most rapid car safety improvements came during a single ten-year period, from 1910 - 1920, where deaths, again, expressed per passenger mile, halved in only ten years.
