An other point is that companies like VW or Toyota own several companies,
so they
can sell the same powertrain and batteries (and R&D for FSD), under a different name,
thus gaming the tax break:
(Don't the Tesla Semi uses the Tesla Model 3 electric motors?)
So why don't Tesla branch out and create new companies like Tesla Junior, Tesla Master, Tesla Executive, Tesla Supersport?
Since Tesla sales are mostly online, this would not be too difficult, for getting another 200,000 cars discount for each brand.
A Low cost Tesla Junior - Model 2 would be sold like the VW ID (e-Golf).
A Sporty Tesla Master - Model 3 and Y would be sold like the Audi e-Tron
A Top of the line Tesla Executive - Model S and X would be sold like a Bentley EV.
A Flagship Tesla Supersport - Roadster would be sold like a Porsche Taycan EV.
A Tesla Outdoor - Pickup Truck would be sold like a Lamborghini Urus.
An Exotic Tesla would be sold like a or Bugatti.
A Tesla Semi would be sold be like a VW - MAN
Note: This is exactly what Hyundai is doing with Kia and Genesis, or Toyota selling Scion, Subaru, Lexus, Mazda, and Chevy with Cadillac...
