Just got a 2018 Forester. Previously had a 2016 Crosstrek and also have a 2018 Legacy. The rear windows in the Legacy and Crosstrek go *all the way* down. Not in Forester--only about 3/4 the way down? My poor little pooch has to stretch his neck like E.T to look out. Is this a safety feature? Can it be turned off? I don't really see how it could be a safety feature, a kid could still easly get out. What am I missing here?
