There's a video on of a woman driving while she uses one hand to film her kids in the backseat . . . then REAR-ENDS someone.



The one part that makes it seem real is that she SWEARS right after it happens . . . and then her daughter REPEATS it.  



But some people think it's staged, as a PSA.  Either way, it's a good reminder you shouldn't do ANYTHING with your cell phone while you're driving. (Search for "Don't Tape and Drive."  She wrecks at :18.  WARNING:  She says the S-word.)
