lots of bounty:
the best way to get lots of bounty is like this-
do you no where the bus station is?
if so go there and get on top of the buses and you cant get busted. make sure you keep an eye behind because some police can get smart and come up behind you.good luck!! =P
{TIPS FOR IT}
-if you want loads of bounty make sure your heat level is about 3-5.
-make sure you have a fast car.
-make sure you havent used the pursuit breakers cause it will cost you heaps.
-the car I recommend for this type of method are-porche carrera GT, SLR meclaren, BMW M3 GTR or a corvette c6
