I went from a Model 3 with HW3 to a Y with HW4. The difference is night and day. FSD actually works in the Y. It’s surprisingly good compared to the old version. I would never have paid for it again but they transferred it to the Y.
Were they running the same version of FSD when you switched, or did the HW4 vehicle already have a newer version?
The HW4 vehicle already had the new version. I only got it about a month ago. I planned to never buy another thing from Elon, but my wife likes the car and we needed a new one. I was feeling very bitter about the previous one because FSD never actually worked. Ignoring the fact that I bought another car from a space nazi, I’m very happy with the new one.
“Tech is rarely supported with software updates after 5-7 years. Tesla Hardware 3 [(HW3)] is entering that zone. It is becoming obsolete and normally, it wouldn’t be a problem, but Tesla sold a Full Self-Driving capability package for up to $15,000 based on this hardware that it never delivered.”
Didn’t the exact same thing happen with HW2?
To answer my own question, yes it did:
Tesla claimed the HW2 suite of sensors and computation provided the necessary equipment to allow FSD at SAE Level 5.
