Or maybe unaware of the damage you've caused.
oft times, the associated electronics damage isn't a complete total failure of an item, but portions of it's functions which aren't so obvious.
For example, an engine control system might not cycle an EGR valve all the times it's supposed to do so. A later EGR fault driveability problem isn't always linked back to a computer failure, but blamed on the EGR valve failure or wearing out.
Or a seat memory circuit has a partial failure, such as one location not working out of the several stored.
Or a fuel control circuit has a partial failure, where it doesn't tip in on light throttle like it used to. Or maybe the car doesn't idle quite right anymore, or come off idle as smoothly as it did previously. Or many other niggling driveability problems which tend to get overlooked.
Or the electronic compass in a Subie won't set a direction.
Or maybe any one of hundreds of controls or functions or portions of them.
With all the computerized electronics functions in the cars, you can damage quite a few and still not notice that you've damaged them because the car still "starts and runs" and the resulting computer problem(s) aren't so obvious to the owner.
