Generic models of propelled particle systems posit that the emergence ofpolar order is driven by the competition between local alignment and noise.Although this notion has been confirmed employing the Boltzmann equation, therange of applicability of this equation remains elusive. We introduce a broadclass of mesoscopic collision rules and analyze the prerequisites for theemergence of polar order in the framework of kinetic theory. Our findingssuggest that a Boltzmann approach is appropriate for weakly aligning systemsbut is incompatible with experiments on cluster forming systems.
