text: Limiting car usage is not just a great way to reduce pollution and keep the planet we call home healthy, but a great way to keep us healthy, both physically and emotionally. Those are just about the best advantages that can come with anything.    A driverless car is a scary concept. Some say that it is completely insane, but that is what they said when Neil Armstrong came up with the idea of walking on the moon, and now walking on the moon is no big deal. In my opinion, with a lot of hard work and problem solving, driverless cars could become the next big thing.
