Brandon Loomis is a rank amateur when it comes to living without a car: Seven Days Without: No car? No sweat? No way - Salt Lake Tribune. It does take time to get used to doing with out and to realize that you are going to have to take more time in order to get to where you want to go. I will say, however, that the premise that Loomis is working under is not mine: I'm not car-less because of economic reasons. I am car-less because of stubbornness and environmental reasons. I am stubborn because I can't see the use in having a car only as a luxury (and not as my main means of transportation) and my environmental reasons are pretty obvious.
While Loomis may be saving money trundling about town in his own car because everything is so close, he is not helping the environment by re-joining the legion of single-drivers. He, in fact, is compounding it.
