I ran from the law....Suckers.
They are usually marked on the radar, it's baically collapsing debris, and only works if the police are right on your tail. The debris will cut down the number of cops chasing you, it depends on how many were caught under the debris. Infractions will also rack up on your rap sheet and different cars (it's not smart to always use the same car, but it can be reduced by changing the physical appearance ). It can be anything from speeding, to Excessive Speeding Property Damage, Ramming a Police Vehicle, Driving Off Road, Resisting Arrest Hit and Run, and Reckless Driving.
