Easier said than done in a lot of American cities and burbs. I’ve tried to go without a car, and it just hasn’t been practical.
I’m on the edge of a denser American metro that actually has a subway, and when I ditched the car for some of my jobs, I added several hours of commute to my day, and it honestly started to wear on me physically.
When I have the money I’ll probably jump over to an EV. It seems like the most reasonable solution for where I live and work.
