To have steroscopic vision you need two cameras with the same optics. Tesla has three front facing cameras, each with a different field of view. And they are too close together.
But they never claimed to have stereo vision. You don’t need that on the road - all the cars are roughly the same size, so it is easy to “guess” the distance to them.
I just wouldn’t trust it with anything when off the road.
They actually have three cameras in the main front-facing unit as of 2020. Before that, I believe they did still have 2.
