It's ironic that this article appears just a few slots above the "the network is untrustable" article about AT&T's support of hacking. The process of keeping an Internet-facing machine safe is a more or less daily battle of 0day patches. This isn't, has never been, and likely never will be possible for consumer electronics because it imposes too much cost on the manufacturer. Automotive software doesn't get updated with the same frequency as desktop software for a bunch of reasons, and it also doesn't get updated indefinitely because there's a distinct end-of-lifecycle for it. TL;DR: The only safe-ish automotive electronics, both now and in the future, are electronics that have no connectivity. It's impossible to feel safe about connected electronics of any sort, and in a realtime control environment like a vehicle, it's frankly irresponsible to permit such connectivity.
