293 Hmmm?

Q: You are driving in a car at a constant speed. On your left side is a drop-off, and on your right side is a fire engine traveling at the same speed as you. In front of you is a galloping horse, which is the same size as your car and you cannot overtake it. Behind you is a galloping zebra. Both the horse and zebra are also traveling at the same speed as you. What must you do to safely get out of this highly dangerous situation?
