Review: The world's first vehicle made in China, the smart rail train, has raised questions about the safety of driverless driving. While it offers numerous benefits such as shorter travel times, lower costs, and flexible routes, concerns arise regarding the ability of artificial intelligence to handle complex road conditions and emergencies. The smart rail train operates without tracks, thanks to China's "virtual track following control" technology. It can accommodate up to 500 passengers and intelligently detects traffic conditions to optimize travel routes. The construction cost and period are significantly reduced compared to traditional rail transit. Although the smart rail has gained popularity, citizens have expressed doubts about its second phase due to potential safety issues associated with autonomous driving. The levels of driving automation range from human control to full autonomy, with questions arising about the reliability of artificial intelligence in complex situations.
