Exactly.
How many of us use a car based navigation system? The one in my car is terrible. How many have one that is connected to the internet?
How many of us use an app as our navigator? Google maps, Hema navigator, etc? Most of us?
The best navigators will always be connected to the net for software updates, roadworks updates, traffic updates, etc.
So if you are operating an autonomous vehicle by navigator, it is likely to be subject to interference.
