If you have a car, you know the convenience of getting in and driving directly to where you want to go. You might enjoy this enough to wonder why you should bother taking public transportation at all. But you can give back and gain so much by taking the train, bus, subway, or ferry. Start with the environmental benefits of leaving your car behind in favor of public transit: reducing carbon emissions and our collective use of non-renewable oil. It can be good for people, too. Without having to fill up at the pump, you can save money on gas and vehicle maintenance. And without having to pay attention to the road, you're free to read a magazine, prepare for a presentation, or study for an exam. When you're sharing a ride on public transit, you can interact with other passengers—or discretely eavesdrop on conversations. You can daydream or doze, solve a crossword puzzle or play a word game with friends on your smartphone. Do it for a day, a week, or simply more often.
