Dashcam video captures the heart-stopping moment a woman jumps from the roof of a moving car into the path of a truck inside a tunnel in Hangzhou, China. The truck driver brakes and swerves just in time, while another tractor-trailer also veers away as the woman lands in traffic. Witnesses say the sudden move nearly caused a multi-vehicle pileup. Authorities say relatives took the woman to a hospital, and police are investigating the incident. ▻
