Tesla owner completes DIY HW4 upgrade; why isn’t Tesla doing it?

A Tesla owner independently upgraded their Autopilot hardware from HW3 to HW4, finding the process relatively straightforward. Tesla has stated that the HW3 to HW4 swap is more complex than HW2 to HW3 because it requires replacing cameras as well as the computer. However, Tesla has not rolled out a large-scale solution to upgrade millions of vehicles with older hardware, despite promising microfactories to facilitate this. This situation frustrates users who purchased the Full Self-Driving (FSD) package, as current hardware and software still do not deliver the promised full autonomy.

• HW4 requires replacing cameras in addition to the computer.
• Tesla promised microfactories for mass upgrades but has not progressed.
