Atlanta gets to be artificially high on the list, next to actual nice cities like Boston and NYC, because it gets a 1 in connectivity.
I guess that's because of our famous busiest airport in the world! Too bad if you want to go anywhere in the city, though.
The public transit system only goes every 20 minutes in a + shape, makes everyone coming from the airport buy an NFC card, and the speakers and upcoming train monitors in every station are unusable and broken. People in Atlanta like driving so much they force everyone else to do it along with them.
