APRS has been used for vehicle tracking for a while (it was first devised in the 80s).
It is dependent on independently operated base stations to relay data to the internet, and since all transmitters contend for the same frequency it may not be feasible in high-use areas. You also need a Ham technician license (35-question written exam).

On the plus side, it's totally free to use.
