When an aircraft becomes involved in a vehicle pursuit, pursuing ground units can fall back and loosely follow the wanted vehicle. The whole objective of using an aircraft is to slow everyone down (including the wanted vehicle) and assure the safety of both police officers and the general public. Ground units, following loosely, can then be in a position to move in for the apprehension when the wanted vehicle stops or is parked. It should be noted that once the aircraft is overhead, it is almost impossible for the vehicle to get away. Many perpetrators understand the futility of fleeing from a pursuing aircraft, so if they realize that an aircraft is involved, they will try to return to a familiar neighborhood, abandon the vehicle and flee inside a large building. If any units are available, they could go the likely areas where the suspects will try to abandon their vehicle.
