Humans have stereoscopic vision

Edit: I'd love to know why I'm being downvoted. Tesla cars guess depth with a neural net. Humans have the hardware for getting this data directly. Unless you either have lidar, radar, or dedicated stereoscopic cameras, you don't have real/accurate depth data. And depth data like that stops your car from plowing into white trucks.

I didn't downvote you, but as I see it human stereoscopic vision is kind of irrelevant.

If you close one eye, do you really feel like your ability to determine depth is significantly impacted?

And even then, the stereo effect is basically negligible at the distances relevant for driving.

A human missing one eye would have no trouble driving, except maybe for the reduced field of view.

This is true. But most of the things perceived while driving are outside of the stereoscopic depth perception ability of humans. IIRC that stops around 20 meters or so.
Unless I've been driving very differently from you, most of the things that I care about the precise distance of are well within 20 meters.

And moreover, it's lucky at best if my Model 3 acknowledges a car 20m away on the preview. It struggles with cars a few feet from me on the diagonal at stoplights.
