A vertical rotating parking lot has been installed near Baijiahu in Nanjing, as seen on Thursday. The new parking lot is 12 metres (39 feet) high and occupies only two parking spaces in width. It has six floors and can hold 12 cars. The new system saves time and effort. It takes only one minute to park your car, which is done by tapping a button on a keypad. The system can rotate when another driver wants to park.
