This video reminds me of a Ford Mustang cutting a bunch of other vehicles on a boulevard . I wasn't one of the cut ones but i saw him changing lanes again and again right in front of other drivers.... then he made it to a Dodge Charger which had to brake a little bit hard to avoid the collision as the light turned red........ yeah, you all guessed it, the Charger was an unmarked police car....

Remember, if you want to do an illegal move on the road, check out for the cars with the lights on top first..
