Panoramic glass roofs have become common with luxury vehicles.
The Lexus RZ electric vehicle comes with a panoramic roof in some trim levels, they do not come with a factory sunshade. Accessory sunshades are available for $400; some owners have made their own sunshades. The Lexus has a selectable opaque feature for the glass to reduce sun load.
Tesla panoramic glass roofs have extra ultraviolet sun light protection but are not completely effective at reducing interior heat, for that a sunshade can be added.
