[QUOTE="SoonerP226, post: 3326836, member: 26737"] I'm not aware of any cars that have that capability built into their systems, but the cellular carriers could provide a location history. They have to know what is connecting to their cell towers for billing purposes, so it all depends on what level of logging they do and how long they keep those logs. For the purposes of fiction, it's not unreasonable to assume that their logging is detailed enough to recreate a location track. The "black box" built into newer cars won't record enough data to be useful; it's basically just a rolling buffer that's constantly having newer data replace older data until some type of predefined event (maybe an airbag deployment) causes it to write that buffer to non-volatile storage. You're only talking a few seconds of data immediately preceding the event, though, not enough to recreate a location track. As was mentioned earlier, planting a GPS-based tracker on the vehicle seems more plausible, even if it's just dropping a cell phone into the car. [/QUOTE]
