Yes, they do, and I’m not sure why. Well, for one it’s easier to throw your garbage out of the window for someone else to deal with. What’s not easy is putting your trash in the map pocket of your car, or God forbid you have a small trash bag in your car, and then emptying it out at the next destination.
The worst litter job I’ve ever seen was a man throwing entire bags of McDonald’s drive-through from of his window. Not sure if he didn’t like the food or maybe his family didn’t appreciate all the hard work he performed that week and he disposed of their dinner in protest of their ungratefulness. Nonetheless, I saw the car rock back and forth and then three large bags of food went flying. They were full bags too, fries burst out and went everywhere. It was quite a spectacle to behold.
