When being chased by the police, open the GPS map. Locate the nearest orange triangle with the pointer and activate the GPS. It will then show a blue arrow and lead you to the Pursuit Breaker. If the cops are directly behind you, they will stop because they "died". However if you are at heat level 4 or higher, the cops (Corvettes) will just dodge the debris. Once the cops have "died" it will then go into Cooldown mode. Then, just wait until you lose them. There is a faster way to do this. If you go into GPS mode (after you have gone into Cooldown mode), there will be a blue-white dotted circle. Activate the GPS for the circle. Drive toward it and make sure that you are exactly in the middle of the circle. Your Cooldown meter should be drop down faster. After the little screen appears, you should be back to normal.
