A GIANT spider is loose in the car! Pull over! This is NO joke!

Open the window (on the other side of the car) and I will just JUMP OUT! Pull over, open the door...I don't care if the car is stopped yet or not! This family was traveling when someone noticed movement on the ceiling of the car. ITS A SPIDER...A BIG SPIDER! This is my worst nightmare. If I was driving, I am not sure we'd make it home alive. My questions is what took them so long to pull over and all get out of the car! At that point, the spider has a new car...he can have it...he's certainly big enough to drive it! Rick
