Technically they say you should be backing into a parking space, but few people do it as it's easier to back out from a small area to a big area. Why black people do it more, don't know.
Though I'm white and always backup into the driveway at home when it's winter as it's easier to see if cars are coming when there's 4-7 foot snow banks on both sides of the driveway. When going to walmart I usually find a spot where two parkings facing each other are empty so I just drive right into the next one, but I wont cycle the whole walmart 15 times in order to find such spot, like some people do.
