This topic has always confused me and I don't understand why more car manufacturers don't make it easier to use the center seat position with LATCH. We have a Nissan and a Honda - according to the chart linked above, we shouldn't be using LATCH with the lower anchors in the center seat position. Is there any safety reason why we shouldn't use LATCH with the seatbelt installation in the center seat? I know it's recommended you use one or the other, not both, but I've never seen a good explanation as to why that is the case.
