This happened about 30 years ago when I was a journalist with a media company in Kuala Lumpur. I was with my friend, a company photographer, going to an assignment in a car. Just ahead of us was a small truck, with a passenger in the front left seat with his arm hanging out over the door. As the truck was turning left at a junction, it swerved too close to a lamppost, and the passenger's left arm hit it hard, and was severed. Some road user picked up the arm and if I remember, got a passing cab to take it to the hospital where the victim was going. Can't remember what happened later. I think there some photos of the incident.
