Here's one part of the article that rang true for me:
As Kingman points out from her own car-free experience, “We ended up
supporting a lot of local businesses, because big box stores and malls were much harder to get to. We bought our groceries every few days, which supported a healthier diet.
I buy the majority of my food from local farmers. I agree that it's healthier, but it also tastes better. The cost is only a little more than I would pay at a chain supermarket, but for me the value of local food is much greater. Being carfree was a big part of the reason that I decided to seek out local food sources.
