that ain't cool. don't pull over for cops, people, EVER! you never know if it's actually carjackers. take this advice and don't blame me when you get involved in a 10 car chase.
this is why when an unmarked cop car is trying to pull you over you're supposed to call the dispatcher and ask if it's a real cop, since the cops are supposed to call in the fact of who they're pulling over. if the dispatcher says its not a cop then you just keep driving and they'll send real cops to jack the fake ones.
