Because software is buggy, even Apples. It's not like you are updating hardware (like your other examples) you are doing a software update so that the software interfaces with the hardware better or fixes bugs.
nowadays your TV if it's a smart tv also gets monthly or quarterly updates too. they just tend to happen in off-peak hours. and car software updates are when you take them in for service.
you aren't doing a fair comparison asking why your X hardware doesn't need updates when comparing mostly hardware with simple software and full operating systems.
