way back
n.—Gloss: the backmost area of a station wagon (British: estate car), usually used for portage or storage. «I dare say that most people who are parents now never rode in a car seat as children. Many of us didn’t even use the car seat belts when riding around town. We scrambled to ride in the “way back” of the family station wagon.» —“Milk has an Expiration Date and so Does Your Car Seat!” by mmcphee Epinions Aug. 31, 2006. (source: Double-Tongued Dictionary)

This explains everything. My father-in-law used this phrase while greeting one of my kids as we picked him up from the airport. My daughter was seated in the last bench of our 12-seater van and he exclaimed, “Hey, way back Audrey! How are you doing?” We use the phrase now to address whomever is sitting in the back bench.
