Does that really add up? If the people who rely on public transportation are not the ones who will be able to afford the new services, how would the new services move money out of public transportation? Are you talking about the people who are currently spending their money on public transportation, but could in fact afford to spend it on some other, more luxurious transportation mode if they so chose? If so, isn't it likely that if they still choose public transportation, out of ideological concerns presumably, they will continue to do so in the future?
I'm not qualified, but I'm guessing that the money will mainly be moved from private car transportation to these new transportation services.
