#22Can't we just stop using the (admittedly convenient) CAN bus for this sort of communication? It was never designed for what people are using it for these days.
Part of the reason cars have gotten more reliable in recent decades is due to this sort of standardization and refinement.
What would you replace it with? If you replaced CAN, you still would need an in car network of some sort. It would have its own layer of security issues to worry about. Mechanics/Service centers would need an entirely new suite of diagnostic tools, this isn't just something you can quit using.

#23That shouldn't be too hard. Disconnect all radios from management computers with an airgap. And if that goes at the cost of some functionality then so be it but the downsides of interconnected systems are heavier than the upsides. At a minimum stick an 'airgap' switch in the dash somewhere and default it to 'on', or label it 'insecure' when off so the users know the risks.
The problem is that doing so removes the ability to do the self parking, or doing something like the remote kill switch that they can invoke in case the vehicle is ever stolen. Me personally, I know how to park and particularly care if my car is stolen..that's my insurance companies problem. So I could live without both of these features, but you can see how some would argue the opposite. I'm sure there are other tie…
The insurance company could make it your problem, by charging you a higher premium for theft coverage than the next customer if your vehicle doesn't have the feature.

#24"But two Democratic senators, Edward Markey of Massachusetts and Richard Blumenthal of Connecticut, have introduced a bill that would force the industry to seal off critical computers and add technology to stop hackers in real time." Why do governments feel the need to dictate the little details? Instead of forcing all car manufacturers to secure cars in the exact same way how about just holding them liable for the c…
Aren't the car manufacturers already liable?

#25My ideal car has no power-anything: no power windows, door locks, brakes or steering. Accessory-wise, just an AM/FM radio with a 1/8" AUX jack, a 12V outlet and some cup holders. 5 or 6 speed manual transmission, unless it's electric.

> What would you replace it with?
Individual wires transmitting analogue signals; differential voltage or current loop, depending on application. Add a bunch of RC filter networks on either side to limit the bandwidth to the kind of signals going over the wire and you got a pretty tight, hardwired system.

Seriously, when can this happen? Is there a cad file on TPB yet? I'd download it.

There is at least one lawsuit over the hackability; so, I guess we will see.

Build yourself a kit car. I'm sure you could get this setup.
