You get behind the wheel of your car, trying to dodge as many falling animals as you can, and start the car to drive away. It's only a moment before you're plowing through the downpour, hitting animals, knocking them aside, and driving over them. Then the car stops in place, abruptly but without jerking you forward, no broken down but simply still.
