I would never get in the car or let someone I didn't know get in mine. With that said, I have to admire your friend (glad she's OK) on her brave stunt. Following them, not so sure, but it is possible she was hoping for the cops to see her? I am sure she knows how dangerous it was and regrets it. Kind of reminds me of the granny here in Chicago that shot the 12 year old punk who tried to break into her house. I know, I know, 12? Hey, they aren't the 12 year olds we remember these days! She didn't kill him, just got him in the shoulder. Go granny! She has offered to mentor him if you can believe that!
