The computer on an EV will tell me the state of the battery. You can ship an ICE over to the best mechanic in the world, and that mechanic won't be able to reliably tell you state of, for example, the bottom end bearings. Not without cracking the engine open, anyway. A compression test will reveal a lot, but it could still break a piston ring tomorrow.

That said, I'd not hesitate to buy a Honda with over 100K miles on the clock. But the point is that checking the state of a singular point of most likely failure (battery) is many orders easier to check than the state of an ICE.

Leak down test, oil pressure, opening the filler cap for blow by, sound... Plenty of accessible options there that will diagnose a bad bottom-end or piston rings. Further, your average Joe can replace crank bearings in an afternoon and many could re-ring an engine with some help from youtube. Your average Honda will need this once every 200-400k miles (14-25 average 14k driving years) with proper oil changes.

There are a lot more components (cells) in a battery pack than rotating components in an average engine. I'm unsure if they're generally individually addressable, but I know they're not designed to be serviced at the cell level. That has you replacing the battery pack any time there is a problem, a many thousands of dollars adventure just in parts. There's also no major differentiator from a software perspective between "the battery is old and has reduced capacity" and "the battery is swelling and has reduced capacity". The latter could lead without warning to a catastrophic failure that would make a ringland failure laughable.

I do appreciate your view is held by many consumers who purchase a new or certified pre-owned car every N years. For those in lower income brackets (including most countries in the world) or who like to buy things that last, electric cars don't seem to carry a huge value proposition over a traditional ICE car.

who like to buy things that last, electric cars don't seem to carry a huge value proposition over a traditional ICE car.

Our Scion xB has over 100K miles on it, and our Leaf is one of the first to roll off the line. We tend to keep things. And I'm perfectly happy with the value proposition of even that early-adopter tech. There's a lot more to EV ownership than just range and battery life. Ten years later, I can hardly wait for our next vehicle that we'll drive the wheels off of...and it will be electric.

EDIT: and if you can get the oil pan off a modern car without removing the engine or at least undoing the mounts and $STUFF so it can be jacked up (thereby cancelling any "in an afternoon" of changing crank bearings), you're a better mechanic than I ever was (and I used to do it for a living).

Having an expert analyse your car by sight and sound is decidedly different than you popping open the OBD2 port in an EV, opening an app on your phone and checking directly what condition the battery is in.
