text: "Smart" cars are very useful and have alot of wonderful benifits to them. These cars will very much likely use less fuel than the average car or taxi. They are less pron to get into accidents than human driven cars. They will take a bit more supplies to make these cars be able to do everything the need to be able to do to handle the real roads, but with all the money saved on fuel and all the money saved on not having as many accidents, it will all be worth it.
