I said EV's have zero regular maintenance costs. And ALL vehicle have tires and wipers, etc. - so how does that matter to this discussion?

So, you claim they are moving (even though they are not) because they wear out? You keep attempting to redefine words, rather than discuss facts.

Just for a concrete example, take the battery in the computer I'm using to write this. Doing cat /proc/acpi/battery/BAT0/info (if you run Linux) gives
design capacity: 84240 mWh
last full capacity: 68190 mWh
so despite a very light use cycle (99% of the time it's in a docking station, running off A/C) the battery has lost capacity over the years.
Now with an IC vehicle, when it wears enough that performance degrades, I can fix it with relative ease. (Though my two current vehicles, 1988 and 2000 models, are still going strong as far as engines are concerned.) Can't (again, AFAIK) do something similar with an EV: when the battery degrades too far, the only fix seems to be a complete replacement. Which, if current usage patterns hold, means that 1) people will junk otherwise perfectly servicable vehicles; and 2) people who'd buy inexpensive 20 year old IC-engined vehicles will have no options.

You are making some sort of deflective straw man argument. Electrons are not "moving parts"; no matter how much you want them to be.
Here are the moving parts unique to an EV:
Motor rotor (1)
Its bearings (2)
Two reduction gears (2)
Their bearings (4)
Then there are the parts they have in common with all cars: the differential, U-joints / CVT joints, wheel / brake hubs and their bearings. Oh, and the wheels.
If you can even count all the moving parts in an ICE, then I think you will have to concede that EV's are MUCH easier to maintain, and understand that they will last MUCH longer.
Batteries will last as long as a typical ICE and/or it's transmission. Individual cells and/or modules can be replaced. You continue to overemphasize this; despite a lack of any evidence.
