Now this is actually a brilliant idea. It would essentially allow Tesla to sell FSD on every car, they’d make more money at zero marginal cost, the cost to the buyer stays the same, and buyers are getting something of value so optically it doesn’t just look like Tesla jacked up prices to offset the tax credit.
We don't know what sort of provision will be in place. Income or any sort of limit on car prices. They could very well do upto limit of $50k and 250k income if his pre-election proposal carries through.
