Yeah, I really don't understand the glass roof, even with Tesla; most people just try to find a way to cover it up. If you are tall, the heat radiates to the top of your head...It sucks. Hopefully Rivian (or someone else) will come up with an easy install cover.Live in Colorado, with sun and altitude year-round it will wreak havoc on an interior of a car and cause way too much A/C utilization. Does the roof blackout? I hear there is no sunshade? It may work well in the Midwest but will cook the interior way over 120 out here most times of the year, and when in the very high elevations, not much insulation? Any input?
