It's all lighthearted hypotheticals until someone you love or you yourself in a moment of inattention make a catastrophic mistake.

In theory, we don't need guardrails on roads. Just stay on the fucking road and if you swerve off it, you'll get a lesson in why that's a bad idea.

In practice, we are primates whose cognitive systems are made of squishy grey goop and we make mistakes all the time. Building systems that turn predictable mistakes into catastrophic consequences is what we used to call "poor engineering".
