    I assume you are referring to the Lorentz transformations. Perhaps if you specified the situation you are thinking of we could be of more help.

    Nope … if A thinks B is going north at c/2, and B thinks C is going north at c/2, and C thinks D is going north at c/2, then A still thinks D is going less than c (how much? :wink:)
