Well If KC posts another response saying the same thing with different words it will be a Jewish Poem.
Well, all I can really do is to keep re-explaining the same stuff in deeper detail, unless you either come up with
some kind of logical counter-argument explaining why the written text directly and indirectly contradicts your idea that this passage is "flavor text" about TW devices.
I think I've established the facts in about as much detail as possible at this point, though, so I'm content to rest my case if you've got nothing else to say on the subject.
It looks like you're at least willing to grudgingly accept that
nobody else in this thread is interpreting the rules the same way you do, and to try to address things in the context of the rules we believe are correct.
To answer the question in the OP....
No, a Vehicle can't be a Focus as per a 'it can be any old tech item held in hand' (not that I agree with the interpretation KC detailed), it is too big and consists of too many parts. No, ever a subsystem of a vehicle can't be a focus, it is not in itself a whole tech item.
It's definitely too big.
Consisting of many parts is not a listed criteria, though.
An ox-cart with only <12 parts wouldn't work because it's too big, but a hand-held computer with hundreds of parts could work.
At least, there's no canon reason why not.
I'd consider certain subsystems to be their own devices.
A gun attached to a vehicle is still a gun, for example, and a radio built into a vehicle is still a radio; either could be removed from the vehicle and still operate just fine, as long as it had a sufficient power source.
Now, perhaps it's possible that a device cannot serve as a spell focus if it's missing its usual power source, BUT that would be speculation not addressed in canon.
There is no mention of whether or not the C-18 and Revolver must be loaded in order to be used to cast Fire Bolt, and I don't see why it would need to be. There is no mention of casting a spell using any of the ammunition or energy from the device.
So if you pulled a car radio out of a car, it'd work.
And while it wouldn't be the most outlandish thing for a GM to house-rule that the radio MUST be pulled out of the car before being able to be used as a spell focus, it would be a house rule.
