Depending on the weather, heated mirrors may be a safety feature. I'd very much like that for rain/foggy days for example.

This comment section went from “I don’t understand why car makers don’t sell a cheap stripped down car without luxuries” to “Heated mirrors and seats are very important” very quickly.

HN comments discovering in real time why the stripped-down base model vehicles don’t actually sell. People like those luxury features and they choose to pay extra for them.
