text: Fewer cars and this rebuilding of cities saves you money and commute time. Just think about all those rising gas prices. You don't need to pay tolls when you walk, or get fined when you run too fast. Prices for parking spots and passing tolls are going up anyway. It's an easier and cheaper alternative to just walk or bike somewhere. Public transportation like buses and subways cost a lot less too. Studies have found that fewer people are buying cars and getting their licenses; it's for a reason.
