In Multiplayer (unknown in Single Player), some cars have no driver and are unobtainable, but they're driving around like there is someone in them. They can be stolen, if the driver-side window is shot out. Some cannot even be obtained by this means. They usually appear after someone has obtained a 3-5 star wanted level. Some pop up at random. They can be seen (listed from most sightings to least) in and around the Dukes area, Bohan, and northern Algonquin. They have no driver, and if the player shoots them, they will not speed away.
