That happened to me before too! Only it was a smallish spider, but to me, even the small spiders are super creapy!! I started to cry and had to pull over and get out until I could find a way to kill it/get it out of the car (As I couldn't drive with IT there....) I have no idea how I got it out, but somehow I did..I was super late to pick my bro up, and he got really mad It really is freaky! I know how you feel!
