It probably just uses the magnetic "rail" to guide it on the road.
SoI I'm guessing it could be replaced by a 5$ GPS reciever
or like, the same fucking wires used for robot mowers
the magnets don't directly move the vehicle, the field it generates is just measured by the sensor on the car to be able to get reliably accurate position data iirc
gps definitely can't provide that level of accuracy reliably
