I realize that on some four doors the rear windows will only roll down halfway or a little more than that, likely for child safety reasons.
However, I im in a rental car right now while mine’s getting fixed, a Dodge Caliber (I hate the thing, fwiw) and the rear windows roll down all the way except just a tiny fraction of window, like about an inch. What purpose could that possibly serve? It isn’t going to keep a child from extending their arms out the window, and it just seems stupid.
If you’re not going to stop the rear window at about halfway down or a little more than that, then why not let it just roll down all the way?
