It's kind of an annoying post anyways. He/she's essentially saying, "I tried to go car-free, hoping to save a bunch of money without being willing to make any changes to my lifestyle."
I got rid of my car in June. I am fortunate to live in a city that's very bike friendly with good car sharing, but I also have family in the suburbs and a desire to go out in the woods from time to time. I use car2go, a car sharing service, maybe once every week or two (about $10/time depending on distance). I invested in over $400 worth of biking supplies (studded tires for winter, a bike trailer for my dog, etc.). I have a neighbor friend whose car I can borrow fairly regularly as needed if it works with his schedule (in fact, due to this car sharing set up we've started dating).
But I definitely don't have the flexibility I once did. It's a sacrifice I'm willing to make for the convenience of being car-free and not having to shovel snow off my car, worry about snow emergencies, pay for insurance or car maintenance, or feel compelled to drive when I don't actually want to drive. I spend less per month on 'car' expenses, but I spend more in buying drinks for friends who drive me places. It's a trade off I'm currently really enjoying.
