> Humans are also able to drive with vision only. Same sentiment as Hotz from comma.ai has. I’ve said this before and I’ll repeat it here. A CMOS sensor is nothing like the human eye both in terms of HW and the SW (ignoring the AI that interprets the signal - I’m talking just in terms of the sensor). Your eye is constantly subconsciously scanning an insanely wide FOV so that not only do you have an insanely high-res image at the center, you have a fairly high fidelity larger FOV that is quite wide. Additionally, the camera will automatically shift its focus insanely fast if there’s any motion in your periphery and start filling in the scene with extremely high fidelity data. It’s hard to really equate the two but some analyses I’ve found on Google estimate the human eye at having hundreds of megapixels worth of fidelity. The Tesla has ~8 1 megapixel cameras. As for the intelligence behind the camera in terms of command and control, the human brain is significantly better. At some point in the future, sure. A pure vision system could be equivalent (actually better) to a human driver. Today it’s probably better in some ways (doesn’t have the attention failure modes that the human brain can suffer) but fatally worse in others (distinguishing the white trailer on a semi right in front with a cloud or understanding there’s a dividor right in front of you). Obviously things are going to get better so I’d bet on a pure vision system in a decade or two will probably work. The problem is Musk’s false advertising and the lives it’s cost. |
