Have separate temp settings for "heat to" and "cool to".
As the weather gets colder, I often want the AC on when I'm driving in the daytime and the heater on when I'm driving at night.
When it's warm outside, I'm dressed for warm weather, and cooling the car to 78° or so is fine. In the evening, I'm dressed for cooler weather, and heating the car to 66° is fine.
Because my Model 3 has only one temp setting, I frequently have to reset it. Sometimes I'm driving at night and suddenly notice the car is trying to heat to 78 degrees. Home thermostats have had separate heating and cooling settings for years.
My car should too. If it did, I'd might never have to touch the temperature control again.
