Earlier quoted context omitted.
When I worked at Apple, I lived about half a mile from campus. I'd often go a week without even getting into my car; I could walk to everything important, including grocery stores. There were three very good bookstores within a 20 minute walk [now all out of business, btw]. I miss that.
I can't imagine life not being that way. I live in NYC and can walk to everything important, or take a short subway ride to anything else. I've gone months without getting in a car- if I ever move I think I'd miss that a lot.
I was actually penalized when I renewed auto insurance for not carrying it for 2 years, despite not owning a car nor driving at all.
Robust public transportation should be a huge initiative for all major cities, and even more so ones that are growing quickly. The efficiencies, environmental impact, and convenience for citizens are too much to ignore.
