Of all the issues with the C7 (and most are minor) the one that concerns me most is the lack of Blind Spot Detection mirrors. The side/rear view on the C7 is horrendous but that is due to the sleek beautiful design that we all admire. No amount of mirror adjustment or even head swiveling can seem to provide safety against side-swiping crashes. I narrowly missed one yesterday when attempting a lane change in my 2014. Why couldn’t GM have installed this? Are any retro fixes available? I sure hope it will be on the new C8.
