Using public transit as your main mode of transportation is not the same as swearing off cars entirely. If you live somewhere with good transit you can get to 99% of the places you want to go without a car with no additional inconvenience. You can take the train to work, bike to the gym, walk to the grocery store, and then when you want to head out to the mountains you can hop into your car (or a rental). You can reap the environmental benefits of switching mostly away from cars without sacrificing your freedom to drive to the small number of destinations that are not convenient to get to by other means.
