Then price to you was just a but more than a bus fare. However the real price to the city works out to about 15x as much as a bus fare. Does your city really want to subsidize this (it would be a similar price for your city to just give you a basic car!)
They did a study for a small- to medium-size town in Germany – based on traffic modelling, it was estimated that an extensive on-demand system with almost 500 on-demand vehicles would only have about the same effect on passenger numbers as simply extending all existing fixed-routes bus routes to run every ten minutes all day (which for a town of that size is a rather good service), but operating the fleet of on-demand vehicles was so expensive that even fully automated on-demand vehicles were significantly more expensive than driver-operated conventional buses (never mind automated conventional buses).
I'm not sure what came of it; but I guess it didn't get adopted by the TfL so it never really became part of the transport system of the city.
