Is this Chinese vehicle a train, or a bus?
China just launched the world's first "autonomous rapid rail transit." It's a driverless "train" that doesn't run on rails. Instead, it uses sensors to create a virtual track on the road.
The vehicle is basically a smarter bus that can hold up to 300 passengers. China hopes the smart bus can help ease traffic jams in the country's urban centers, which cost billions of dollars every year.
We're on board!
