For me, the biggest benefit is the mental load I no longer have. I used to have to think about maintenance, MOT schedule, road tax scheduling, insurance scheduling, renewing my parking certificate, how much I drink, where I’m going to park, did I run out of time on the parking meter, is there traffic on my route, where are the road works…
The mental energy I’d waste just to deal with a car was massive. There’s still mental energy with public transit, like what is the schedule and which bus do I need to be on to make it in time, and what do I do if a stop isn’t near my destination, but it’s a lot less mental load than having a car.
Single person instance hoster here! I love that I know what service I’m interacting with, I control what that instance does and chooses who to federated with, and I’m unlikely to get defederated due to some other idiots bad comments or brigading.
