Funny thing, my other two SUVs both have full glass roofs. They also have integrated sunshades that can be retracted. I literally keep the sunshades deployed at all times. It gets pretty warm here in San Diego.
Admittedly, I’m somewhat disappointed by the visor position on the Air. I love the big windshield but the effect is significantly diminished by the visor being in the way. There might as well be a bar across the top of the windshield and have the glass be a separate piece with this arrangement. I understand the reasoning behind it (easy easy to flip down at a moment’s notice) which makes perfect sense to me, but yet when I was recently in a Model X I was floored by what a big difference it makes. For the Air, I bought the accessory mesh parts and installed them. I haven’t removed them since.
I’m not sure if they will have a metal roof on certain variants of the Gravity. I don’t think anyone outside of Lucid has that answer at this time. To reach the price point that they desire, that might become necessary. Large pieces of curved glass are very expensive to manufacture and also to warranty.
If they do have a large piece of glass like was shown at the LA Auto Show, I at least hope that they have a way to cover it without having to insert a separate piece of mesh like we do in the Air. I’d love some sort of deployable sunshade. Even cooler would be glass that can be made opaque at the touch of a button but certainly this would be significantly more expensive.
