A little more of an official response from Rivian on Twitter albeit still lacking detail.
Thanks! Ironically, I did see the new FAQ section about week or so ago. I only gleaned it and clearly missed or forgot about the roof options entry. Even though the tweet appears to be a copy-n-pasted from the FAQ, the question posed in the FAQ is not EAV specific unlike the twitter question which is for the SUV.They mention that in their "NEW" FAQ in their website. If you haven't checked it out yet, I would take a look... There are a couple new details.
Well, you might be. From the "Thoughts on Glass Roof" thread where I originally made this post, @skyote had posted the following:My guess is that they won't offer a sun screen/shade because of the electrochromic glass option (user-controlled transparency....well, at least between opaque and transparent--I don't know if there are options to have any middle-of-the-road setting). I wouldn't mind being incorrect with that guess, though.
