text: If a car free society is ideal, how come we don't have it yet? Currently, we still depend greatly on cars; giving them up wholly is a very radical change. However, governments are working into it slowly. On top of car-free towns like Vauban and car-free holidays like in Bogota, car-free cities are being planned. These cities would be very dense, making it easier to get around with a bike, on foot, or on public buses and metrorails rather than in a private car. This will reduce pollution greatly, spawn a healthier population, and even support local business growth now that local restaurants will be a walk away from one's home. Even today, cities have been favoring alternative transportation with tolls on cars that exempt bikes.
