I would like to suggest that the approach to relativity is backward.
By this I mean that Einstein, and almost everyone since whether agreeing with Einstein or arguing against him, begin with the notion of the invariance of the speed of light and then create an argument about some kinematic situation. Only later did Einstein attempt to modify Newton's laws so that they would fit his discussion and the conclusions he reached during his kinematic thought experiments.
For reference, here is a version of his postulates.
1. First postulate (invariance of c)
2. Second postulate (principle of relativity)
If one basically revereses their approach to relativity then it would seem logical to select fundamental laws of physics and then require that all use these same laws. the initial problem is then "How does one select the fundamental laws?" This question was not addressed by Einstein, and to my knowledge, by no one since.
For reasons discussed elsewhere, I sought to begin with the 1st and 2nd laws of thermodynamics and this is a partial list of what I was able to show:
Based upon the above it would seem that starting to think about kinematic experiments before considering the laws of dynamicsis the wrong way to go. Yet if one starts with the thermodynamic laws one must conclude that light must travel at the absolute velocity and all must see the same absolute velocity, but by developing transformations based upon the kinematic argument as special relativity did, the transformations do not see the separation of the force driven velocity from the relative velocity within the transformations.
Recognizing that the relative velocity is different from the force driven velocity is important when attempting to understand phenomena involving relatively moving observers.
