Two thugs in an alley in Manhattan held up an unidentified man. When the thieves departed with his possessions, the man quickly gave chase. He had almost caught one when the thief managed to force his way into an empty taxicab stopped at a traffic light. The Peerless Transport Company owned the cab.
The thief pointed his gun at the driver's head and ordered him to drive on. The driver started to follow the directions while closely pursued by a posse of good citizens, but then suddenly jammed on the brakes and jumped out of the car to safety.
The thief also jumped out, but the car traveled on, injuring Mrs. Cordas and her two children. The Cordases then brought an action for damages, claiming that the cab driver was negligent in jumping to safety and leaving the moving vehicle uncontrolled. Was the cab driver negligent? Explain.
