literally, an EV will tell you a range estimate based on current charge level (and include ambient/battery temperature in that estimate, maybe even recent terrain/driving behavior).
the piston seals in the cylinders of an ICE car should be (nearly?) air tight. As the car is used the pistons/seals wear down reducing engine performance and efficiency. It can get so bad that the car won’t even run, I once test drove a car that started fine but would die at idle speed when warm. It’s very expensive to fix, most cars are probably scrap at that point.
special diagnostic tools are needed to get that information from an ICE, whereas an EV will, at the very least, display right on the dash"fully charged : x miles"
I’m not sure if there’s hard data on whether engines or batteries generally last longer though, cuz a modern engine will get to 200k miles before it needs to rebuild. But batteries don’t care about miles so much as charge cycles - but your main point about it being very easy to check is true, since you just measure the voltage coming off the battery, how quickly it changes, etc which doesn’t require any disassembly and on most EVs there will be a diagnostic option to run a fairly accurate self test.
edit: I later looked this up and found that modern EV battery life is equivalent to about 300k miles of driving, and even if you treat it like shit it’ll still beat an engine, generally speaking. EV electric motors last about as long, so assuming there isn’t a manufacturing defect/crash damage, any EV drivetrain from the past decade is probably good.
I would be so afraid of buying a used EV and its battery just being fucked
It’s easier to check battery health than engine compression nowadays

Teslas are known to lie though
I don’t even know what engine compression is

more compression makes your car faster and more fuel efficient, but requires better gas and makes everything hotter.
