I would love to ditch my car but it’s impossible in my city and I have no power to change it. I could move I guess but choosing lack of car over my friends and family feels a bit drastic.
But yes, getting old sucks and walking takes some discipline.
and it also requires you to fully buy in to the city-centric lifestyle. Whether you like it or not there will always be a lot of people that don't want to live in an urban center or even a small town. For them, personal transportation is non-negotiable. Even people who live within walkable towns or cities will often prefer to have a car so that they can access other locations and services whenever they feel like it without having to rent or limit themselves to places accessible by mass transit. Cars just aren't going away, nor should we wish them to. I'm all for building more walkable and human scale environments, I enjoy them as much as the next person but I also want those places connected by good roads so that I can access, or leave, any of them freely.
