Ten seconds is apparently all it takes to empty a subway car full of passengers. <br />That’s what happened on August 9 at 9:34pm when an unidentified foreigner entered a subway car on Line 2 of the Shanghai Metro at Jinke Station. After taking a seat, the man was seen shifting towards his right, his head nearly touching the shoulder of the middle-aged woman sitting next to him. <br />Soon after, the man suddenly fell on the floor and appeared to have lost consciousness. <br />The first reaction from the five passengers sitting across from the foreigner was to run away. As seen in a surveillance video on board the subway (below), all passengers rushed out of the car within ten seconds of the man falling to the ground.
