As it turns out it doesn’t actually cost that much on regular transit, there’s an AIRPORT SURCHARGE because it’s an “airport train”.
No wonder Americans don’t use public transit, even when the system exists it’s ridiculously difficult and expensive to use.
the big thing is that most roads are paved and regularly maintained these days, medieval britain for example had an absurd density of roads (higher than today) but most of them were just shitty tracks for carts to rumble along. Like back then an actually paved road was kind of on the same level as railways are now, a massive investment that makes things so much better
