I guess it depends a lot on the quality of your public transport.
Where I come from (not the US), in cities you have a bus/tram/metro every 5-10 minutes, bringing you everywhere, for a fraction of the cost of an Uber (which is why nobody uses Uber).
Places that don't have good public transport are quite remote, usually there are no Uber there, and if there is a taxi service it is quite far away so you have to wait and it's expensive.
Finally, moving one person at a time in a big heavy vehicle is less energy-efficient than having them in public transport (or better: taking the bike!). So public transport + bike again wins there, I think.
But again, it depends on the quality of your public service.
