Completely irrelevant. I'm not interested in public transport across vast areas from city to city, I can drive or fly for those (very rare) occasions.

Public transport is most useful for the hyper-local day-to-day movement. I'd just want good reliable public transport within my town and neighboring areas.

(Actually I'd prefer to just bike, which requires secure bike parking in all destinations. I can already bike anywhere in town, but my bike will get stolen if I stop anywhere to shop or eat, so I can't do that.)
