I find the thermostat mode only works on overcast days or at night as the sun contributes so much feeling of warmth when driving (in California) that the heating and cooling thermostat doesn't work well.

A sun load sensor mostly solves this, they used to be a high end feature but it's becoming more common.

High end? It's on my 15 year old Suzuki. I only know that because the diagnostics told my mechanic it's broken and he replaced it once :)

It may just not be advertised.

Thus more common, it’s still not an every model of every manufacturer thing. Tracking incoming angle is also less common etc.

I don't think my 15 year old Suzuki has it :(

Oh, neat, never knew about that!

As someone mentioned a Lexus in the thread, my memory popped up the fact that most expensive models have thermostat corrected for the sun position and probably current weather.
