already there. i work for chrysler, this year we will have wi-fi in vehicles, and right now there are certain challengers and other vehicles that can be tracked by computer. soon all cars will have a module with wireless communication that can be accessed by pods on phone poles. police will be able to shut your vehicle down. your speed can be tracked and all data of the vehicle can be seen by me
im not joking either, this technology is already being used in protos right now, when i was in school in new york they showed us data of a challenger with this in it. its pretty cool.
