Apparently the panoramic roof was originally designed without a sunshade and the sunshade was added after feedback from the forums last year. Now that people in the test drives have seen how effectively the panoramic roof blocks both heat, light, and by extrapolation UV, it may be that the enthusiasm for the sunshade has waned, particularly since the roof bar which will accept the retrofitted shade is not getting good reviews. Would people now prefer dropping the sunshade if it would make the roof bar less obtrusive, more aesthetic and easier to blend its fit and finish? I'm interested in current forum feedback on this, maybe Tesla would be too. (I understand there is possible legal concern over UV exposure without a sunshade but the other glass in the car likely transmits even more UV so it really should not be an issue.)
