It really doesn't, it's just a side effect. We already have massive tailgating issues across the US, and most folks have zero idea what the limits of their commuter EV are. Kind of a recipe for disaster.
There are some quirks to setting up SMB so Time Machine is happy, but I have had great success with ZFS+SMB hosting my TM backups. Have been running for a little over a month and nothing is corrupt. Self hosting is still somewhat hard, I don't blame you for bailing on something so critical to uptime in the first place.
That is assuming that the only reason the government wouldn't pay out FDIC insurance is collapse of the dollar (or that refusal to pay would cause the collapse of the dollar). I don't think that is the case. I would put the odds of the US government doing something stupid much higher than the collapse of either the dollar or Apple.
That's kind of my point, it's not natural that Microsoft is still around after how much negative they have done for the tech industry. Xbox is their golden goose. VIDEO GAMES?
Come on, let's not act like Windows, in its 11th iteration, is not a steaming pile of shit. I don't know how so many of you defend such a garbage company.
Comma.ai is another great example of CANBUS hacking. I'm a bit worried there are a bunch of zero days sitting out there on CAN implementations. It's such a complicated system.
Newer Toyotas (Rav4 Prime and 2022+ Model years) are not compatible with Comma due to encryption, I would guess that probably also defeats this attack.
On a RAV4 Prime (or RAV4 PHEV for those outside of North America), these ECUs reportedly have "ECU Security Key" (A SecOC implementation) or signed/authenticated CAN bus commands since replacing them requires a check in with a Toyota server to "Update ECU Security Key" :
ECM
Hybrid vehicle control ECU
Forward recognition camera
No. 2 skid control ECU (brake actuator assembly)
Rack and pinion power steering gear assembly
Clearance warning ECU assembly
Steering sensor
Central gateway ECU (network gateway ECU)
Combination meter assembly
Airbag sensor assembly

There's nothing about smart key in here specifically. Not sure on later "ECU Security Key" vehicles though. If someone were to look up replacement instructions for the Smart Key ECU on Toyota's TechInfo, and if it has ECU Security Key update as a step or not, that could answer this.
SecOC is based on symmetric key cryptography. If an ECU is replaced and has a new key, this key will have to be taught to all other ECU's in the vehicle communicating with it.
I believe either the data from the adaptive cruise radar, or the data to control the steering is encrypted. I don't know if lock controls are. It was a small but important subset
It's really only troublesome on stuff that has a radio. Like it's not great that you can take over an electronic device with brief physical access, but the physical access reduces the scope of the problem a lot.
> This is something I ask every audiophile I ever meet. Why not use digital audio at all times and convert to analog as late as possible in the audio pipeline instead lf buying ten thousand dollar cables? No one ever gave me a good answer...
If they want to keep the signal pure analog, that is enough of a reason.

Why would they want that? It's possible to perfectly reconstruct the original signal. The sampling theorem states that analog and digital audio are equivalent given a high enough sampling rate.
> If a function x(t) contains no frequencies higher than B hertz, then it can be completely determined from its ordinates at a sequence of points spaced less than 1/2B seconds apart.
I don't see the point of analog signals anywhere in the pipeline other than in a DAC whose output drives the actual speakers.
There's no crime in simplifying the signal chain to reduce complexity. Theorems are great, but implementations are what matter and usually where things fall apart.
