While self-driving cars are new, self-parking cars are not. Putting that relatively old capability on a wish list would be silly. But what about a self-driving car that could tool around the mall parking lot looking for a space for itself? Engineers in South Korea have figured out a way to bring data from sensors, cameras and that old-school movement-meter, the odometer, together to help a self-driving car become a self-parking car. The car looks for the painted lines that mean "parking space," then it determines if there's an obstacle in that space — like, say, another car. When it finds a parking space with nothing in it, it tells the driver, who can choose to take the spot or look for a better one. Of course, the car has to be able to see the spot, so night parking is still up to the humans.
