Beijing's endorsement of Tesla's "Full Self-Driving" technology resulted in the stock experiencing its largest one-day percentage gain in over three years. Tesla's collaboration with Baidu, a Chinese search giant, on mapping and navigation seeks to advance autonomous driving in China. However, the competition in the Chinese market is fierce, with other companies such as Huawei and XPeng also developing self-driving systems. Fully autonomous vehicles still face regulatory obstacles globally, hampering their widespread adoption. The success of Tesla's FSD technology in China will determine its competitiveness against established rivals in the region.
