Good question.
What can go wrong if you are carjacked?

Glad I drive a cute little manual shift Fiat 500. The thugs aren’t interested in my tiny toy car and can’t drive a stick.
Don’t become complacent. If they attempt a carjacking and your car is a stick, a carjacker may just murder you because they have been thwarted.
I did read that article at the link. I can’t imagine the horror that couple endured. Sickening.
