At the 2002 Brazilian Grand Prix, Ribeiro was involved in a potentially serious incident. During the morning warm-up on race day Sunday, Enrique Bernoldi crashed his Arrows in Turn 2. When Ribeiro, the driver of the Medical Car, went out to check on Bernoldi, he opened the door to the car. Just as he opened it, Nick Heidfeld came along in his Sauber and smashed into the open door. Both Ribeiro and Heidfeld were uninjured.
