Very helpful! But dare I ask, what is the rationale for holding R&D and SG&A static in the second half of this year when everything above on the Income Statement is expanding? Doesn't the combination of GF-3, Model Y, Solar Tiles, the pick-up, Semi, FSD, and Robo-Taxis require additional investment in R&D? Same concern about essentially no increase in SG&A when much of the growth in deliveries will be in markets where the sales/service/parts/supercharger infrastructure needs to expand to support the larger fleet?
