So in your rubber ruler world.
You need to transform speeds between two frames?
There is not transformation needed.

Of course you need to transform speed between the two frames, otherwise they
would be THE SAME SPEED.

How simple is this ?

No,
(A) made a physical measurement,
(B) can only make an abstract measurement.

No, (B) has no perfect valid "physical" measurement at all.
It has an abstract method and if such abstract method does
not show the same as a true "physical" measurement does,
then there is something wrong with your "abstracting" method.

Oh go on then tell me how (A) can measure the seperation between two lines
without moving.
