The idea that Tesla could get fully auto vehicles out of the existing Model 3s their building today is laughable. Even top-tier AV companies, with larger teams and far more advanced sensors, can't. There's a huge difference between working 95% of the time, and working well enough for a full auto fleet, and Tesla won't get there with pure cameras and a single front-facing radar. It's possible they could retrofit the old cars with new hardware, but other AV companies have suggested that retrofits aren't automotive-grade enough to last over time (sensor mounts drift too much, etc).
