I think cars should be added to minecraft because it would be a faster way to get from Point A to Point B. If it was added the recipe would probably be the shape of a minecart with a chest in the middle of the shape for the gas tank. It would probably run on coal and it would be controlled be WASD. It would probably have the shape of a minecart retextured to look like a mustang because it is my favorite type of car! It would really improve upon minecraft because it can get you from Point A to Point B faster than walking and faster than minecart.
