I think automakers are discounting rear window visibility partly because rear view cameras are becoming more and more common. Honda is making them standard in all vehicles this model year.They're certainly upping their game and I will test drive one. They have knob-equipped infotainment, so they score points over the civic there.
I really dislike this trend towards less and less visibility and headroom, which appears to be case again in this new cruze by the looks of that rear window. I've test driven several compacts now, and in all of them I felt the visibility was poor and in a few of them my head is touching, or near touching the roof, putting it in my field of vision when driving like wearing a ballcap. The salesmen try to dismiss it as that's just how compacts are, but I have probably 4 inches of headroom in my 2001 civic and far noticeably better visibility, especially out the rear.
