XPENG puts its advanced self-driving AI to the ultimate test: chauffeuring professional car enthusiast and Grand Tour host Richard Hammond. The company’s XNGP system navigates tight city streets and tricky parking with a level of calm precision that seems almost alien to a man famous for his… enthusiastic driving. One can only assume Hammond is off-camera, desperately searching for a handbrake to yank, a common feeling for those new to advanced driver-assistance.
