Escape the cops in the Shelby GT500™ (Single Player)
First, you'll have to win the new Most Wanted event and take down the Shelby GT500 to earn the car. Once you've done that, all 3 Jack Spots will be unlocked and you can jump to them from the Easy Drive menu. The event is available as soon as you've purchased the DLC.
Once you're in the Shelby GT500, find a cop, indicated by a blue arrow on the mini-map. Get some speed, and go for a takedown. Doing this starts a pursuit and disables the cop at the same time. Any other cops will usually spawn behind you, outside of the pursuit radius, so you can just drive away as fast as you can and end the pursuit almost immediately.
