Think about it this way: a month after Vision Pro hits the markets and floods Apple's servers with user data they shutter the alleged car project. Coincidence?
Yes, it is an accidental coincidence.
The more likely reason was the coming increase in import tariffs on Chinese-made EVs. In November 2023, the U.S. House Select Committee on Strategic Competition between the United States and the Chinese Communist Party urged the Office of the United States Trade Representative to hike tariffs on Chinese-made vehicles. By December 2023, it was being reported that the Biden administration was considering increasing the tariffs from 25% to 100%. Biden announced a tariff increase to 100% in May 2024.
Increasing the tariff from 25% to 100% increases the landed cost of the Apple car by 60%, which in turn would have increased the sticker price by 60%. I suspect the impact of that would be quite a bit more significant to Project Titan than any unrelated data received from AVP sensors.
The timing of the cancellation lines up well with the institution of the tariffs. Shutting down a project as large as Titan would have required BOD discussion and approval. Given that Apple's shareholder meeting was on February 28, 2024, it is reasonable to assume that there was a BOD meeting sometime in January or early February. Surely Apple's Board of Directors is well connected enough to know by January 2024 that the tariff was going to be raised. Board members would have already been briefed by the time of the meeting about the coming tariffs and the impact on financial projections.
Project Titan was shut down on February 27 2024.
