Abstract: A plurality of vehicles with cameras and other sensors collect images and other data as a normal event, or upon demand, or when requested to do so by another vehicle, an occupant or a service center. Images may be permanently stored in the vehicles and indexed in a directory at a service center, so that the images may selectively sent to the service center or another vehicle without consuming storage space at the service center. When the service center is managing sufficient current data for an area, the service center generates a suspension signal to discard or instruct vehicles not to send further images from that area.
