Yup, it's something I think people need to experience.

I lived in the UK for 2 years without a car and it ultimately did not negatively impact me (other than needing to memorize local bus routes). I lived in towns as small as 10000 people (Newtown, Wales) and they had both a connected rail system and a couple of bus routes serving the town and connecting it to other towns.

Buses absolutely can work in even quiet rural locations, they just need to be properly funded and prioritized. They also need to be subsidized. The American notion that public transit needs to either run net zero or turn a profit is backwards and fundamentally stopping it from working well.
