It's pretty crazy to think that we live in an age, where physical buttons are a noteworthy mention by car publications. Not surprising that Cadillac has decided to do away with the tactile controls, as most owners expressed their hatred of trying to use them properly while driving. Do we know if there are any changes to the lighting amongst different trim levels. It seems at though there are completely different set ups between the test mules we've seen. Maybe that's just been the natural progression of the concept?
