> The reason there's not more public transit is because the economics are terrible.

The reason we don't have roads is because the economics are terrible. The government gets $0 per trip [1], but it costs billions of dollars a year in operating expenses.

Wait, that's not how it works.

[1] Federal gas taxes don't count, because those go to the Highway Trust Fund which funds road construction, which is not an operating expense. State gas taxes may vary. Although toll roads also properly charge people user fees, although for some reason, lots of drivers complain about how expensive tolls are...

But you can't ignore the financials. SF Muni's $3.62 cost per passenger mile is atrocious. At that price point, it's cheaper to charter a helicopter. I'm not kidding. You could literally charter a 20-seat Airbus H175 helicopter to fly people around for $2.50 per passenger mile. And you'd get there faster.

If public transit is less cost-effective than taking a helicopter, then something is clearly broken.

Of course, this is what happens when there's no profit motive. If we weren't making the marginal cost of using a road zero, and they had to compete with each other, and the people running transit wanted to make money rather than satisfy the requirements of a law, transit would be cheaper. That's how it is in all the places in the world where transit is really good.

Or it wouldn’t exist at all in in this form…

Dude. Public transit can carry hundreds of thousands (millions even). How many helicopters you planning on having? How many landing pads? Where are they going to go? You going to spin up a municipal ATC? This is silly.

Is it just because of an artificial low denominator?

wallst07 5 hours ago | parent [-]

It's circular:

* Few take it because it doesn't meet their need [low denominator]

* Let's spend money to make it meet people's need [numerator goes up]

...

Good luck scaling that “solution!”

Perhaps what’s broken is your financial analysis.

Please show his error.

hcknwscommenter 2 hours ago | parent [-]

The error is completely ignoring the negative economic externalities of NOT having public transportation and the positive economic and environmental externalities of having public transportation.

Roads are fully paid for by road users (i.e. everyone).

hcknwscommenter 2 hours ago | parent | next [-]

huh? Public transportation is fully paid for by everyone too.

Yes, but most people don't use public transit.

Not really. That’s a tautology anyway.
