How exactly is it separated?<p>I imagine the ideal solution would be using two airgapped computers, one for the main car system, one for the media stuff, and then keep the servers from which they receive updates, and the authorization for those servers completely separated as well, with the updates done by different people, too.<p>But I imagine the vast majority of car makers don&#x27;t do anything <i>close</i> to that, and probably not even Tesla does it like that. BMW wasn&#x27;t even sending its OTA updates over HTTPS until 2 years ago.<p>I imagine most right now, if they even isolate the media and the main systems at all, probably do it through virtualization to &quot;cut costs&quot;, so they don&#x27;t even use two different chips. Heck, they may even use &quot;containers&quot; to cut costs even further.<p>And this is why I won&#x27;t be a self-driving car beta tester in the first 10 years. You just can&#x27;t trust these guys when up until now they didn&#x27;t even have a clue about software security, to do this properly. And it&#x27;s probably why &quot;Silicon Valley car makers&quot; will end up winning over the traditional car makers eventually, too.
