As far as I can tell here the ghost portion is basically a non-sequiter. The waymo vehicle called the cops because it detected e passengers had a gun. The vehicle did not know or care about its status as a ghost gun or not. I'm sure that the Waymo terms of service prohibit carrying weapons into the vehicle. I'm pretty sure that if you were brandishing a realistic looking enough gun, an Uber driver would kick you out and call the cops as well.
