True.

If relative velocity is measured using light, it is pretty obvious that
problems will arise near and beyond light speed. This has caused great
confusion in the physics ranks.

Not true. It seems to cause great confusion only among those who do not
understand physics or don't take the time to understand.

If relative velocity is measured using an infinite grid of synched clocks,
(simulating instantaneous communication) these problems disappear.

But such a grid doesn't exist. Nor is is possible even as a
hypothetical, to construct such a grid. The problem hinges on precisely
how the clocks are synched.

I have provided a way to absolutely synch remote clocks and set up such a grid.
