I don't want an always connected car; I want it to be completely able to work off the grid.

- waiseristy 6y agoIf it makes you feel better, all of the actual car stuff, ECU's BMU's TCU's, etc will remain not-smart for a long while longer. Worst case, your head unit bricks and the HUD flashes a bunch of lights at you
- serf 6y agoit's all fine as long as you make the assumption that the CAN-bus network all of the components share isn't exploitable. unfortunately that was shown not to be the case since at least 2010.[0] The worst case is potentially much worse than a bricked head-unit. The worst-case is potentially a sizable loss of human life. Note : I don't have a solution. The industry is obviously trending towards connectivity; I just wish to elucidate that it's far from solved from a security & liability standpoint.

- waiseristy 6y agoI have so far only seen the various car networks compromised through physical access to the vehicles diagnosis ports. It's safe to say all bets are off once you start plugging physical things into the car. Doesn't mean a head unit couldn't be compromised and start flooding the specific can bus its sitting on with packets, but usually head units are treated with a bit more care than the rest of the cars networks. Trying to jump can networks through one of the gateways, I don't think would be an easy task either.

- waiseristy 6y agoOh jeez good find. I don't know what Tesla was thinking with that gateway!
- crossroadsguy 6y agoThen you can simply paint over it.
- pdx6 6y agoEven connected cars need to run in offline mode. There’s no way a car with Starlink navigation is going to work in an empty parking garage or a tunnel. I can’t even get YouTube music to stream over LTE all the time when I drive across town — so smart caching is another frontier to develop.
