You do see how proposing banning maps with traffic updates tanks the whole concept, right?
I wouldn’t either. But I don’t think that means I should mandate my preferences be extended to all by banning the damn thing.
Simpler: mandate a network kill switch that doesn’t unnecessarily compromise functionality. (You would have to be creative about anti-theft tracking functions. But this is solvable.)
Something can be functional but useless
Edit, or rather.. functional but unused
You have it on your phone already, the car has no reason to have its own, with its own network connection.
