Most bus systems in the US are wildly unprofitable and quite costly. My local system is just under $10 per unlinked trip (i.e. get one on bus). That makes getting from point A to point B not much cheaper to provide than Uber because it will usually involve a transfer.
Everyone would be better off in an Uber type system but there's no appetite or budget to subsidize rides at the level people would use it
Don't calculate the amortized (over a reasonable 30 years if you also ignore inflation and major maintenance/refurbishment costs) capex of the proposed Dallas red line northern extension, seen in a per-passenger-mile figure.....
(I got 54ct per passenger mile just in capex (well, a capex-based view on the cost of having the track there and operable; costs from direct wear and tear of running trains and electricity and the trains themselves are additional)...)
