A similar thing happened when I was observing and on the way to a diabetic hypo. Blonde lady in a huge 4x4 (make your own jokes/comments) decided to come through a road wide enough for one even though we were charging down the street on lights and sirens. Don't think she noticed the police car 2 cars behind her, who immediately put his own lights on and pulled her further down the street. Much laughter after the swearing.
