Samantha Ronson -- Call Linds Back Later!
While it's not quite as dumb as trying to escape from a hit and run in a car with your face on it, Sam Ronson driving away from a club on her cell phone as a cop waved her on is up there on the idiot scale.
For all you non-Californians -- yes, it's now against the law here to talk in the car without goin' handsfree.
