I'm fairly certain that Musk said all cars produced after a certain date would have the HW3 computer in them. I bought my second Model 3 on that assumption. But I did not buy FSD, and my car, which was produced after the cutoff date, ended up with HW2.5, because I think they had production issues with HW3, or just wanted to get rid of the 2.5 chips they had left. I get why they did what they did. I understand the argument that "you only require HW3 for FSD, and you'll get it for free if you buy FSD". However, Musk clearly promised one thing, and silently delivered something else. If he had not promised the HW3 computer, nobody would complain (probably not true, people like to complain about everything, but their complaints would be less justified). There are differences in performance which will likely roll out in the future that would make Autopilot better with the HW3 vs 2.5 computer. Even if it's something as meaningless as random sign visualizations. I believe if you've got a HW3 car without FSD, you still get the neat party trick visualizations, which you don't get with HW2.5. Again, completely irrelevant if the HW3 chip wasn't promised in all cars made after May xx 2019.
