I’d love to see some data on your claim that most people use Uber Pool or Lyft Line, because I’m not sure that’s the reality. There’s been a lot of critical reporting on the Uber Pool experience. This Motherboard article is just one example.
I’m not saying that everyone should be taking the bus or that the bus is always the best solution. I do think on-demand services could play an important role in some cases, though I’m not sure the Uber model is the best one for such uses. I would also say that not everyone relies on buses, and that subways and trams can be even better public transit solution.
I agree that there will be a transportation revolution of sorts when self-driving cars become readily available, but I’m not convinced it will be such a swift transition. I encounter a lot of people who are still wary of electric vehicles, let alone giving up their control over the machine. I think the fleet model is superior to the personal ownership model with self-driving vehicles, though I would like to see them added as a new public offering than being the purview of private companies. I also think we need to have a serious debate about transportation in cities. Do we want to keep giving over so much space to single-person vehicles, or should we take it back to use for public spaces and communal transportation solutions?
Naked Capitalism has published a five-part series on the economics of Uber (unfortunately too late to include as an aspect of this article) and you may be interested in it, as it sheds light on the lack of profitability in the current business model, and how fares are subsidized with billions in losses and VC money to try to achieve a monopoly postion.
