Car Jacking: Do you lock your car doors immediately upon entering your car?

[refugen3]

I know this is an old thread, but I just got an e-mail the other day that convinced me otherwise. I don't always lock my doors depending on where I am.
This e-mail got me to thinking.... I guess there's a few wackos who thought about how to get in a locked car. When they see you in the vehicle they will come up to the window and ask you to roll it down trying to give you money they say you dropped.
Don't fall for it ladies, it's just another scam!
