> No, wait...I know the answer to this one because our Nissan Leaf quit getting updates when the 3G was shut off, and I've not taken it back to the dealer in several years. And the answer is...nothing happens. With your specific example, nothing happened, which is the best case scenario, yes? The problem is the potential for inconvenience and disaster is there. I do not look forward to the day when my auto manufacturer forgets to renew a domain name and all of a sudden every single car by that maker cannot start its engine because it can't connect to HQ. It's a contrived example, sure, but it's not out of the realm of possibility.
