I took my kiddos out for a walk yesterday and happened to look up as a car was passing, going about 35 mph on a major street. It was a guy driving a convertible Mustang with the top down, and in the backseat was a girl about the size of a 7 yr. old, and she was FF in a convertible carseat. The top of her head was well above the back of it (and above the back of the car's seat), and she was leaning forward by about 6 inches. There was NO HARNESS or seatbelt on her shoulders. They went by pretty quickly, but I'm assuming he either didn't harness her in at all, or just put it around her legs. It's one of those situations when you wonder why they even bothered to use a carseat.
