Another unintended (or maybe intended) effect: cheap cabs.
Without cab drivers, there's no reason for the antiquated medallion system. That would lead to more cabs. Without medallion costs, drivers, tips, presumably cheaper insurance, and more efficient route-finding -- it should also be much cheaper.
