Most Bounty possible:
Try to start a pursuit near the bus depot. Then run through the glass and up the ramp on the right. Go outside on the roof and stay there. The police will only go up there if you start to go down. You cannot be busted and the helicopter cannot push you off. Doing this you can get all time milestones and get A LOT of bounty. (supplied by: blueviper12321)
