Ye sadly...
Though I'd imagine that connectivity, at least on Tesla as an example, is because of the self-driving part to stream huge machine learning data to the car.

However, considering what's being done where people can self host their AI, yea we're reaching to a point where even self driving cars don't necessarily need to be connected to a server.

Now here's an interesting thought for the future:
Open source electric self-driving cars
Shit will be wild x3
