Even without getting out of the vision sense there are features of vision Tesla doesn’t properly try to replicate. Depth perception for example (it does DP very differently to humans).
You also do use your ears when driving.
- gizajob 1y agoDeaf people can drive fine.
- vbezhenar 1y agoOne-eyed people are allowed to drive.
- scrollaway 1y agoWhat’s your point? I was answering a question, not making a statement about any disabilities.
- vbezhenar 1y agoMy point is that "hardware" depth perception is not necessary for successful driving. Just one camera should be enough, rest is algorithms.
- ModernMech 1y agoEyes are not cameras they are extensions of the brain. That people can drive with one eye is not a "proof of concept" that cars should be able to drive with one camera. You'll need a human brain to go along with it. Unfortunately for Tesla, they seem to be short on supply of those at the moment.
- rogerrogerr 1y agoSo your assertion is that a human with access to arbitrarily good camera feeds could not drive a car at level 5? That something magical is happening because the eyes are close topographically to the brain? Sounds implausible.
- ModernMech 1y agoHow does the human consume the arbitrarily good camera feeds? > That something magical is happening because the eyes are close topographically to the brain? It sounds to me like you have to study what eyes actually are. It's not about proximity or magic, they are a part of your brain, and we're only beginning to understand their complexities. Eyes are not just sensory organs, so the analogy to cameras is way off. They are able to discern edges, motion, color, and shapes, as well as correct errors before your brain even is even aware. In robotics, we only get this kind of information after the camera image has been sent through a perception pipeline, often incurring a round trip through some sort of AI and a GPU at this point. > Sounds implausible. Musk just spent billions of dollars and the better part of a decade trying to prove the conjecture that "cameras are sufficient", and now he's waving the white flag. So however implausible it sounds, it's now more implausible than ever that cameras alone are sufficient.
- JumpCrisscross 1y ago> your assertion is that a human with access to arbitrarily good camera feeds could not drive a car at level 5? No. I live in snow country. Folks with vestibular issues are advised to pull over in snowstorms because sometimes the only indication that you have perpendicular velocity and are approaching a slide off the road or spin is that sense. My Subaru has on more than one occasion noticed a car before I did based on radar. Vision only was a neat bet. But it will cost Tesla first to market status generally and especially in cities, where regulators should have fair scepticism about a company openly trying to do self driving on the cheap.
- rogerrogerr 1y agoTeslas definitely have accelerometers/gyros, and have access to the torque and RPM on every wheel. It has a much better picture of the 3D motion of the car relative to the road than any human driver.
- ModernMech 1y agoDynamics don't help when you are blinded by the sun or can't discern the broadside of a firetruck.
- dtj1123 1y agoOne eyed, deaf people can drive
- mlindner 1y agoTeslas have and use microphones.
- scrollaway 1y agoGp asked about specifically vision only approach. Vision only means no microphones, regardless of whether Tesla has any… What is up with hn today? Was there a mass stroke?
- rogerrogerr 1y ago“Vision-only” colloquially means no LIDAR and other expensive sensors, not the exclusion of microphones (which are hilariously cheap).
- rogerrogerr 1y agoBinocular depth perception stops being useful somewhere around 10 meters. Your brain is mostly driving using the “computed” depth perception based on the flat image it’s getting. Same way Tesla is getting a depth map. Provable by one-eyed people being able to drive just fine, as could you with one eye covered.
