Personally, I'd *much* rather have the Mod x windshield on my Mod 3 than a traditional sunroof. It's as close as you can get to being in a convertible (or helicopter cockpit, as Elon mentioned) without being outside. Something that affects every second behind the wheel. Some thoughts on why this may be both economically feasible and production efficient. - Every car has a windshield and economies of scale would quickly take over. - Sunroofs require a separate manufacturing step to cut the existing roof and install the mechanism. Elon has stated that simplifying production is a key goal/requirement for Mod 3. - Opening sunroofs add cost, mechanical complexity, and potential for more leaks. - On the latest earnings call, Elon mentioned something about (paraphrasing) "having worked out supplier/production issues around the Mod X windshield" - If Tesla has, and is willing to share any patents on this windshield, the cost to replace would be competitive, due to numerous potential suppliers. - It would be a huge differentiating factor over the Bolt, and other (supposedly) competitive offerings in the same space. - IT is just WAY, WAY cooler and more immersive than any sunroof. Anybody see it differently?
