I suspect physicists have fully understood Lorentz transformations. That is why John find spacetime diagrams, 4-vectors, invariant length, proper time, invariant mass, et cetera to be *vastly easier*.

Just ask some whether Lorentz transformation is real or apparent; there may not be consensus. Then you may ask what do they understand by *real*. Physicists should be honest that they still do not fully understand relativity. What most understand well is the mathematics behind.
