Tesla just enabled in the last few months the option for people to upload data to them. Determining which data to upload is its own problem as well.
Tesla has an enormous amount of data at their disposal. The recent change concerned video footage from the onboard cameras.
From what I've learned, lidar and radar are typically used for object detection (i.e., avoiding other cars; perhaps augmented with camera data), while cameras are used for things like lane detection and traffic sign detection. If Tesla is trying to solve the same hard problems as everyone else, using weaker equipment, I wouldn't bet on them having a lot of success.
Also, kind of the point of this article is that Waymo has a test area where they can get real data along with the ground truth. That seems much more valuable than unlabeled/random data.
Did you mean Tesla never captured data before that? If yes then I disagree. Sorry.

Tesla just put out there an opt-in upload of video data 3 months ago. And even then it is not clear how useful that data is. Especially since a v2 of the autopilot hardware was recently announced.
