Actually he may be forcing the lanes-full optimal mode to arise. If one or a few drivers in the empty lane start pacing the cars in the full lane, cars will build up behind them. When they arrive at the end of their lane, the drivers in the full lane won't be so ready to block merges (since nobody was cheating by racing down to the end.) Perhaps this could trigger an outbreak of zipper-merging.
