By the way, that analysis on the ~$80B of US tax benefits for the Semi is arguably very conservative because it considers only the Semi, but not any future derivatives Tesla may make. The 30%/$40k/incremental cost credit applies to any qualified commercial clean vehicles with gross vehicle weight rating (GVWR) of at least 14k pounds. The Tesla Semi's GVWR is 82k lbs. I guess it's perhaps 10k lbs at most for the Cybertruck tri-motor based on Tesla saying the Cybertruck weighs about the same as an F-150, which is 7k lbs GVWR. So there is a solid market in between Cybertruck and Semi that Tesla could go for between now and 2032.
American vehicle classifications define Class 4 as starting at 14k lbs GVWR. Tesla Semi is meant for the Class 8 heavy segment, but Tesla currently has not revealed any products for Class 4 through 7, which Statista says has about the same total sales volume in the US as Class 8.

Classes 4 and 5 could basically be covered by a supersized heavy-duty Cybertruck. The Ram 4500 is an example of a Class 4 truck.

Any vehicle with a high proportion of the cost structure in battery costs will benefit disproportionately from the ~$50/kWh battery subsidies as well, and this would go for that middle commercial trucking segment. A Model Y with an 80 kWh battery at $100/kWh is $8k battery cost out of total maybe $36k cost, so maybe about 20% of the cost structure is battery. At the other extreme, at 1 MWh the Semi battery would cost $100k. I don't know what the rest of the Semi costs, but it's probably far less than this. Commercial trucks in general have more to gain than consumer passenger vehicles do from the Advanced Manufacturing Tax Credit.
All of this is of course contingent upon
- me having accurately understood the law as an amateur reading it
- how long the law actually stays on the books as-is
- how much truck production volume Tesla can actually push out in the next 10 years
