Walker rescues a lady and a little girl from a car that is dangling over the edge of a bridge. But if the car was balanced on the bridge, then pulling the lady out of the front seat would have caused the car to topple over. He should have climbed onto the front of the car and then told the lady to get her daughter out of the back seat first and put her outside the car. Then the lady climb out of the car. And then Walker could climb off of the front of the car and let it fall off the bridge.
