You've got two cars. These harnesses come with one seatbelt tether. What to do? Looks like it's time for some math! Buy another Black & Grey Seatbelt Loop Tether in 10", and wham - now you've got two. The exact same number of cars you have. Wait, what's that? You actually have three cars? Math still has you covered: just buy two more. POW. Math could do this all day.
