Exactly. Why would you ever drive around with your passenger door unlocked in a city? I'll have to ask a friend of mine - she did it in a downtown area and ended up running drugs for thugs for a couple of hours until they finally released her.
Do you think perhaps he opened the passenger door to let the woman into the car, and a guy jumped in instead? After all, he would never admit that...Right?
OMG, she is lucky to be alive!
