It seems like you've made a pretty compelling case on your own re: ditching the car. do it!

As for me: Born and raised in the suburbs, so always lived a very car-centric life (including a stint in the Bay Area). Moved to Hoboken in 2006, and, like you, my car basically sat in the garage all week, with weekend trips to visit family.

Sandy hit, and I lost the car to the flood. Just assumed I'd replace it because... well, because I always had a car! One month goes by, then another. I realize... I don't miss the car at all.

It's now been 10 years, and I still don't miss it (I live DTJC, which isn't quite as convenient as Hoboken re: walkability, but is obviously excellent in this regard).
