In China, sleeping in ordinary passenger cars with folded rear seats gained popularity after the October holidays. As of end-June, the country had 476 million motor vehicles, including 48.97 million new energy vehicles. Travelers report costs: a family of three spent 1,689 yuan over six days, another spent 500 yuan for six nights. Automakers offer 'one-touch bed' and 'camping mode' features. Experts cite risks: an unbelted lying passenger can be killed in a crash, and illegal seat removal carries a 500 yuan fine and possible insurance denial.
