Humans can drive perfectly well with monocular vision. Plenty of people either only have one eye, or don't integrate 3D for some reason.

The variance on human driving ability is higher than we would accept from a machine, but I have two friends who don't have stereoscopic vision, and I trust both of them to drive me

Human eyes are a lot more advanced than whatever cameras Tesla is mounting in their vehicles. (much better dynamic range, higher resolution, higher low light sensitivity, extremely precise movement detection for judging relative speeds, extremely fast and high precision targeting, etc)
