Eh, I feel like that's a rather small factor compared to the main reason we experience traffic jams (tragedy of the commons) and ants do not: >"Traffic jams are ubiquitous in human society where individuals are pursuing their own personal objective," the authors explain. "In contrast, ants share a common goal: the survival of the colony, thus they are expected to act cooperatively to optimise food return." If everyone drove 40mph during rush hour, we'd be well within capacity even with increased drivership. When everyone tries to go 65+mph, that's when things slow down to 5mph. Prisoner's dilemma here, not the limits of acceleration.
