From what I've heard firsthand Autopilot still steadily improves, irrespective of what people say about their favourite sensing modalities...
You can tell apart grass and green carpet with a simple formula. You can coint trees without machine learning. Yoi can detect which plants are whilting, land that is wet from land that is dry. All of that is easy with the right sensors - becauae they have more data than an RGB camera can produce.
I know people that work with mutispectral imagery, they can tell you that pixel N45 has a spesific substance - concrete, steel or wood - jusy from spectra alone. Thye dont need to know what pixels around it are showing, or classify objects.
It's not like Waymo dropped a LiDAR onto the roofs of their vehicles and started driving unsupervised in traffic the next day. Nor Cruise, nor Uber. The sensing is just a small part of the whole system.
Karpathy is one of the world's top self driving engineers. This isn't a vacuous argument. People are driving with just vision every single day. The part we're missing is the ChatGPT moment on the computational side.
