text: Not only would the environment improve drastically, but people would also save money from not having to buy gas! If you pay $3.50 for a gallon of gas, that can add up extremely quick. Imagine all the alternatives you could use that money for instead of gas. Why pay for oil when you can simply ride a bike for free? Biking and walking rather than driving is much healthier for your physical state as well. Altogether, people will be much happier and at a better state of mind with cars banished from every day life.
