Has centralised quality control for taxi drivers worked somewhere? Yes. I can provide you with multiple examples. Use a cab in Singapore or anywhere in Japan and be amazed. The "cabs are terrible" argument seems to me to be a very localized view. Terrible cabs exist. So does fantastic service via the most efficient route by a driver who actually knows the city.
