"Ever since I moved to San Diego last year without owning a car, people have felt sorry for me. They offer me rides. They wonder where I buy groceries. They ask me how I feel about being nature-deprived. They ask me how I can stand to ride the bus. I usually smile and nod and acknowledge what they are saying and tell them it really isn’t so bad. I rarely tell them that they are making a fundamental mistake: They are equating owning a car with using a car."
