Even that can be shown to be a result of the relativity principle.

A.R. Lee and T.M. Kalotas, "Lorentz transformations from the 
first postulate", American Journal of Physics 43:5 (1975).

    "We present in this paper a derivation of the Lorentz
     transformation by invoking the principle of relativity
     alone, without resorting to the a priori assumption of the
     existence of a universal limiting velocity. Such a velocity
     is shown to be a necessary consequence of the first
     postulate, and the fact that it is not infinite is borne out
     by experiment."

Also see section 11.10 beginning on page 38 of the following book 
chapter.
