Steal the entire luggage you find! You are driving a blue mini cooper with the British flag on top. That makes it really easy for the cops to find out where you are and follow you around. You want to keep an eye on the mini map too, so you know where to go. Green circles tell you where the packages are, and you need to pick them up. Run into them to do so. Once you have the luggage, follow the arrow on the screen to get back to base.
