When the cops are chasing you go to south fortuna(in wolfs territory) and there is a parkinglot there you can go in and speed around. The cops will either stay out and wait for you or come in.If they come in just speed around in circles and eventually you will run into them and disable their car.
What you should do is save after each time you don't get busted and then if you do then you can just load it back up also this works with blacklist dudes save it first then challenge them and if you don't get their pinkslip just load it back up and try again I've got all of them!! I think theyre random aswell wherever they appear
To quickly add up to your style points, choose Quick Race in the main menu. Make sure you have loaded your game file before going to Quick Race.
Choose your favorite Drift course (I personally prefer the second drift track) and set it for 10 Laps. If you have mastered your drifting techniques, you can easily score tens of thousands of style points per race.
