Real Autopilot also needs constant attention
Newer “real” autopilot systems absolutely do not need constant attention. Many of them can do full landing sequences now. The definition would match what people commonly use it for, not what it was “originally”. Most people believe autopilot to be that it pilots itself automatically. There is 0 intuition about what a pilot actually does in the cockpit for most normal people. And technology bares out that thought process as autopilot in it’s modern form can actually do 99% of flying, where take-off and landing isn’t exempted anymore.
If you’re just careening down the highway at 80, you’re not really giving your car a fair chance to let you know that it’s really in a disabled state now are you?
It’s just common sense that after a major impact you should evaluate the safety of continuing in your current state. Stopping and doing the bare minimum of just looking at your car would be the first step of that process.
