Mobile models aim to mimic human motion. Real traces aim at the same target. However, the latters are specific. They relate to a country or a region or smaller geographical places. Also, they cover at most few months of duration. In cons, Mobility models approach is more general in space and time for taking advantage of Social Theory. Mobile models are used in mobile networks routing protocols for testing purpose. To enhance random and pseudo-random mobility models, user social behavior has been introduced. Global results have already been published which demonstrates the realism of such models versus random and pseudo-random ones. In this paper, more in depth results which demonstrate with surprising deviations how far are random and pseudo-random mobility models from realistic motions, are given. By the way, we assess that taking into account social behaviors borrowed from Social Theory are more general and timeless, i.e. to our sense more realistic than real traces analysis.
