I love to carpool. We live in Vermont–a rural state where people drive many miles; possibly the most per capita in the country—yet we only own one car. My colleagues graciously drive me to work even though they know that they are unlikely to ever get a ride from me (though I always offer gas money and pay for gas whenever we stop). I have organized the carpool schedule, and would prefer to own zero cars. Yet, according to this article, carpooling is now unpopular, and the carpooling rate is falling. Car ownership, and accompanying convenience, is too common, urban planning and sprawl requiring driving, and driving is relatively inexpensive.
