Maybe in California :) In other places you need defrost, windshield defog etc.

I regularly cross our (small) mountains on holidays and that means temperature and humidity outside can change every 20 min on a trip as you go from a depression to a mountain pass and back to a different depression with a different weather.

The target temperature control stays unmoved, but i randomly have to turn on and off the defog, for example. Can't keep the defog on all the time because it pushes a ton of hot air to the windshield and then in my face, rather keep it off when i don't need it.

Hey speaking of fog, do Teslas even have fog lights? How many layers of menu do you have to go through to turn them on and off?

Newer cars read the outside temperature, and adjust the auto. I don’t know if they sense condensation on the inside. I know that they sense water on the outside to automatically engage wipers.

I have found even the best ones though, to get the rear defrost right, but fail to get front defrost correct in high humidity conditions that aren’t just normal rain. (Very dense fog, snow, sleet ).

Subaru front facing cameras just shut off the eye sight system when the window fogs. The defrost selection is a button, which means it's computer controlled.

In theory the computer knows when it needs defrost.
