Any EV truck or full-size SUV below $55k would be massively underpriced, the base Lightning included and Ford will likely not produce too many of those because they are surely losing big money on them. The Lightning Lariat at $70k, I don't know how they're making money at that price either when a truck of that size with that battery pack and interior is <$5k more than a Model Y LR. I expect the Cybertruck to be priced significantly above $80k.
I don't think the bill is designed to benefit any one manufacturer, it's designed to bring manufacturing out of China and push prices lower. The other aspects of the bill providing credits directly to companies for domestic manufacturing etc would also allow these companies to slash prices, fit into lower categories, and still come out ahead.
