Fear of public spaces or even being in the same space as strangers isn’t “liking different things”, it’s a psychological problem - albeit one that a lot of people experience due to modern society being very atomised.
Not everyone who prefers more personal space has psychological problems. Why is it so difficult for you to understand? Nuance matters. I commute by train, I enjoy being around people, but I use car when I want to get around on my own time, even if train is available.
Commuting to work by train but driving around otherwise is very common, but it's usually because train lines are oriented about CBD trips, but less so for cross-suburb trips.
Are you saying you'd use a car for non-work trips even when the train would be more convenient?
Yes, that’s what I’m saying. I feel energetic when around people when going to work, but want the opposite when I’m not. I also like quietness inside the car, and the ability to detour along the route.
