I'm not sure what the article is supposed to be saying, but geofencing autonomous vehicles does not make them level 5, it makes them level 4 with planning tools. Navigation is not the issue. Large scale mapping using visual only features is pretty much a solved problem. I worked at a company that did this, Apple, Facebook, google, Niantic and a bunch of others all have this ability. The biggest issue here is not that knowing where you are, but what is in the way. Sensors to figure out what is in the way, and if thats a real obstacle or a shadow is the hard part. combine that with working out what other road users are doing ( essentially body language for cars) and thats the main impediment to level 4/5 autonomy.
