You point out one of the key things about making public transport work well as an alternative: frequency and reliability . And I don't mean reliability in the sense that it doesn't break down, I mean in the sense that you can rely that the service will be offered, no matter when. Now the funny part is that it's probably a lot easier to make a self driving train, airplane or bus on a controlled, dedicated lane than a self driving car to increase frequency and extend running hours.
