Why does UPS driving around the block?

I've never had it explained to me and my logic can't come up with the reason why. UPS drops of a package and drives to the corner and turns right. Within a minute I see the truck driving up the street a block over, turns right, and drives right past my driveway, then drives to the corner and turns left. Couldn't they have turned left after leaving my driveway and saved driving around the block? No wonder why they charge so much. lol
