Not really. In reality, even the buses of England for example end up driving so many trips relatively or completely empty (to provide adequate service so that you could do without a car) that they end up producing more emissions per kilometre compared to personal vehicles – you can't do that with incredibly low costs, nor can you calculate the costs by thinking of only the full buses, when that's hardly the complete picture.
