To each their own, but hard to grasp why. It's one the most expensive assets you own. Why wouldn't you want to monitor it at least?

Do you also not have house monitoring (you don't need to control every light switch (which can be useful to have lights on when you get back home), but things like temperature, humidity, power use, air quality, water use/leaks is far cheaper than 1 insurance claim).

Different person, but I don't want a car that has an app precisely because it's so expensive. Cell phones her replaced way more often, and the people running the app stores are very aggressive about not supporting old apps. So within maybe half the life of the car, the app will no longer install.
