Correct, there is no "error" ...

I agree.

And you know this to be true how, by your hundreds of hours of actual
flight experience and contact with hundreds of real pilots?

Pilots don't often admit doing stupid things, unless they are so stupid that
they don't realize that they are doing stupid things. However, people around
them notice, and sometimes accident reports mention it.

The relatively high accident statistics of private pilots demonstrate that
they are doing lots of stupid things as a group, although obviously there are
both stupid and smart private pilots out there.

The reality is most pilots these days are "casual" about flight planning
because the use of computer based flight planners make it a trivial task and
not the onerous task you seem to think it is.

Even with computers available, a significant number of pilots will not bother
to plan. Fuel exhaustion, for example, is still a very common cause of
incidents and accidents, and it's trivial to avoid with a bit of planning.

The fact that real pilots are people and not always 100% perfect in their
every action is irrelevant to the original point of what YOU know and
what YOU do.

You've already acknowledged that I'm correct.

Given you don't know a thing about how to do flight planning, anything
you have to say about the topic, such as the "best" route from point A
to point B, is worthless.

See above. There are facts, which in this case are generally correct when I
relate them, and there are opinions, which aren't worth much.
