Other mfr have the electrochromatic roofs, porsche for exampleI wouldn't say that's consensus at all. I like things bright - certainly don't mind sunlight. Don't want the heat necessarily, but supposedly the coating on this glass helps with that.
But I agree; I've wondered why we don't see the same electronically-dimmable glass they use on the Boeing Dreamliner more often. Would be amazing on this roof!
