He's going to be losing money on every truck

It's really not rare at all for automakers to sell their flagship cars at a loss because of the huge amount of organic advertising the cars bring in on the road. The Porsche 911, Cadillac CTS-V, and Dodge Demon (amongst plenty of others) were all sold at build-to-sale losses at MSRP, but they have the effect of people seeing them on the road and saying "Wow, that cool car says 'Porsche' on the back of it, and this crossover says 'Porsche' on the back of it. It must be cool, too!" Meanwhile, the profits made off Cayenne sales more than make up for the loss from a few thousand 911 sales per year.

What I see happening is, after this run of Cybertrucks are sold, the Cybertruck we see today will enter limited production and Tesla will sell a Cybertruck-lite vehicle designed with cheaper, streamlines production lines.
