After a while, certain high usage routes will be noticed in the rideshare data. It will become obvious which streets and destinations could be optimally served with high capacity buses. Now is the time to bring in bus routes. Setup these bus routes and offer a discount for using them.
The current system isn't working, we need to try something different.
As far as I can tell many people are using public transport, including buses, so it seems to work to some extend.
Rail does much better because it's usually only built where it can be filled, and is electrified.
