> Seattle used to have an area of downtown where you could ride the bus for free. (You could ride within the area free, but paid if you rode out of the area or started your ride outside of the area.) We have this in Perth, Western Australia—we call them "CAT" (Central Area Transit) buses. Any bus within the CBD is also free though ("Free Transit Zone"; FTZ), which is great if you're heading to a client's office and want to take the bus down the Terrace. Our CAT buses and FTZ have existed for years and have not become makeshift homeless shelters. My evidence is only anecdotal (across ~10 years), but I've never seen any homeless people setting up shop on a bus. There are obviously other factors at play here (transport police, better welfare system, 1.9m vs 3.9m people) that are likely making it different from Seattle, however (and these also reinforce your argument).
