No it doesn‘t. What‘s terrifying is the previous non-FSD code that just centers the car in the lane and will hit anything protruding into the lane. There is little reason to believe that the vision will fail worse than before or that hand rolled control code can do a better job based on wrong and unreliable input data from a net.
Additionally this does not preclude a safety check around the outputs, preventing, for example, an extreme acceleration. This would be similar to any checks put on ChatGPT output.
I wonder how they will handle the previous visualization though. Maybe it would make sense to also predict the visualization from the same network based on labeling the data (perhaps using the old methods) but unless that is somehow checked against the control decisions, it will not instill the same confidence or feeling of understanding in the user. But that doesn‘t mean that the driving is worse.
- AlexandrB 3y ago> What‘s terrifying is the previous non-FSD code that just centers the car in the lane and will hit anything protruding into the lane. Are you sure this is what happened before? I've definitely seen Teslas avoiding obstacles in the road in various YouTube videos. Even "classic" (non neural net) robotics navigation systems can avoid static obstacles in their path pretty reliably.
- quonn 3y agoWell, the non FSD autopilot always does this for me. It would certainly hit things regularly. It does recognize moving cars but it would have hit countless parked cars on the right side had I not intervened.
- iknowstuff 3y agoAutopilot is entirely different from FSD.
- quonn 3y agoIt is not entirely different because the classic Autopilot was migrated from radar to vision-only and that surely was done by sharing some code. However the classic autopilot is outdated by 4 years. But my point was not about Autopilot vs. FSD but about the fact that the C++ control code is often rather stupid and unlikely to be as robust as end-to-end learning.
- iknowstuff 3y agoSome object detection code maybe, but behavior is entirely different. Zero code overlap
- zaptrem 3y agoCurrently it appears the new planner net is not trained directly on video but on the semantic labels from the current gen perception system (e.g., BEV Lanes/Vehicles/VRUs). Accordingly, they still show them on the screen.
