You stated " however the observer in (B)
wouldn't agree that the lines are 1 mile apart."

I did not make that statement, you did.
so...
It is you that should give a reason for such.

If I were trying to "physically measure" something like such
I would turn around and stop the ship and physically measure
it in reality, so I would not have any problems
with the measurement being a "non physical" abstraction instead
that could be wrong compared to the physical reality of the
physical measurement.


I want to hear "your version" of why observer (B)
would not agree to the lines being 1 mile apart
since you stated such.
