At what speed? Is there a distinction between these L4 and L5 levels and speed? Is a L3 at idle speed equivalent to an L5 at highway speed?

- tsimionescu 5y agoIf all it took to take an L2 AI and make it L5 were reducing top speed, you'd see a lot more L5 AIs around. The biggest problem with most self-driving cars is that they are easily fooled by various images, since they have extremely simplistic image classifiers to work with, rather than hugely specialized mamallian visual cortexes. Speed of processing is one aspect, but not nearly the only one. The Tesla that ran over that cyclist crossing that street at night wasn't missing reaction time, it simply didn't recognize the cyclist as an obstacle for whatever reason. Now as far as I understand, lidar mostly fixes these false negatives (in good weather conditions), but at the cost of more false positives - and here speed could be a bigger help. Even so, L4 and L5 would require planning skills and understanding of other traffic participants and road conditions that are still beyond us, at any speed. Note that the CEO of Waymo has plainly stated that L5 is not achievable with current sensor technologies. Perhaps at some extreme low speeds (probably closer to human walking speed than 20mph) L2 could work as L3, but I think that's about it.
