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.
It’s written on their gmaps screenshot: 53 mins.
Also worth noting that the listed bike route requires riding on a 70MPH highway, which doesn’t have a shoulder, sidewalk, side street, or bike path. If I were going to avoid that highway, (because let’s be real, I’d be dead on day 1 after being hit by a car,) then it would be about two hours of cycling.
