Full SelfDriving
By midApril 2023, it was time for Musk to try the new neural(神经系统的)network planner. He sat in the driver's seat next to Ashok Elluswamy, Tesla's director of Autopilot software. Three members of the Autopilot team got in the back. As they prepared to leave Musk selected a location on the map for the car to go to and took his hands off the wheel.
When the car turned onto the main road, the first scary challenge arose: a bicyclist was heading their way. On its own, the car yielded,just as a human would have done. For 25 minutes, the car drove on fast roads and neighborhood streets, handling complex turns and avoiding cyclists, walkers and pets. Musk never touched the wheel. Only a couple of times did he tap the accelerator when he thought the car was being overly cautious. At one point the car conducted an operation that he thought was better than he would have done. "Oh, wow," he said, "even my human neural network failed here, but the car did the right thing." He was very pleased.
"Amazing work, guys," Musk said at the end. "This is really impressive." They all then went to the weekly meeting of the Autopilot team. At the meeting. Musk declared that they should move their resources to push the new system forward.
During the discussion, Musk was interested in a key fact the team had discovered: The neural network did not work well until it had been trained on at least a million video clips(片段). This gave Tesla a big advantage over other car and AI companies.
Four months later, the new system was ready to replace the old approach and become the basis of FSD 12, which Tesla plans to release as soon as regulators approve. There is one problem still to overcome: human drivers, even the best, usually relax traffic rules, and the new FSD (Full SelfDriving), by design, imitates what humans do. For example, more than 95% of humans creep slowly through stop signs, rather than coming to a complete stop. The National Highway Safety Board is currently studying whether that should be permissible for selfdriving cars as well.
FSD 12 has got the official permission for sales.
