Backing up carelessly

On quite a few occasions, I've noticed some people backing out of their driveways or parking lots without looking backwards to see if the coast was clear of pedestrians or traffic. It's mostly old people that can't turn their body or head enough to look back like they should. This includes some middle age people too, because of their stomach being so big that it presses against the steering wheel which prevents them from turning to look backwards. Then there's the teenagers who keep on talking to someone in the car or on the phone and backs up at the same time. I almost got hit by an idiot backing out of his driveway when I went to the store this morning.
