I suspect they don't wear helmets or seatbelts either. Sigh. The "I'm so proud and ignorant of unnecessarily risky behaviors" meme is tiring.

The Meta dev model of diff reviews merge into main (rebase style) after automated tests run is pretty good.

Also, staging and canary, gradual, exponential prod deployment/rollback approaches help derisk change too.

Finally, have real, tested backups and restore processes (not replicated copies) and ability to rollback.
