Pre-2023 Tesla Hardware Won’t Enable Full Self-Driving, Musk Confirms

Elon Musk told an earnings call that Tesla cars built before 2023 cannot achieve unsupervised Full Self-Driving due to hardware limitations (Hardware 3), and while a retrofit to Hardware 4 might be possible, it would require exchanging the car’s computer and cameras. Tesla plans micro‑factories to handle such hardware upgrades, signaling a major initiative for retrofitting existing vehicles rather than relying on software updates alone.
