If all your arguments and thought processes are based upon math, then
you are a mathematician even if you claim to be a physicist.

Yes, Tom, that is what mathematicians BELIEVE. However, Einstein
discovered that speed and velocity can also be measured with
respect to Nature's MAXIMUM allowed speed, which is the speed
of light. Measuring speeds relative to the speed of light gives you
a TRUE speed. Measuring speeds relative to some "coordinate
system" gives you a mathematical conclusion, which might have
nothing to do with reality.

Declarations of your beliefs mean nothing, Tom. Do you deny that speeds
CAN be measured relative to the speed of light? It cannot be denied,
so your insistence on measuring speeds relative to some "coordinate
system" just shows that you have DOGMATIC BELIEFS which conflict
with reality and prevent you from doing things correctly.

Declarations of your beliefs mean nothing, Tom. The truck IS moving.
That means emissions from the radar gun will hit the walls at c+v or c-v.
And those photon emissions "reflected" from the walls will hit the radar gun
at c-v or c+v, which will cause the gun to compute the speed of the wall as zero.
All that is needed to measure the speed of a truck from inside the
truck is a way to perform only ONE measurement. My paper explains
how that can be done: https://vixra.org/pdf/2010.0141v2.pdf
