Damn that sounds dystopian. In germany I can visit literally every village and city with public transport. It's not very punctual or reliable depending on the route and length of the trip. Weekend buses into small villages are also only a couple times per Day. But it's definitely possible. In cities I think you can get to every adress without needing to walk very much. Usually I have to walk 5-10mins when I visit someone with public transport. On average I say you have to plan for 30-60minute delay every couple days.

I prefer to ride a bike, which you cna also takes everywhere, some paths may be loud and/or shitty though. But I think every village/city has a fair share of beatiful bike paths especially in the forests. Forests are also everywhere I don't think I have ever been further than 30mins walking distance from a forest.
