Yes, I understand the concept of a best practice, and why breaking it is bad.

But that's not the same as being unpredictable. Those are orthogonal complaints, and nothing in your quote suggests that the "death wish" flying was more unpredictable.

And we already know that these cars act super cautious, the opposite of acting like they have a death with.

So that quote has no useful information that we could transfer to the car situation.
