I agree completely that's what you do in cold weather. I do that every morning with my car. But after 3+ hours in the car, it's pretty unlikely that you'd lower the temperature at that point.
EDIT: Downvotes? Really? If the car's climate control is controlled entirely by a thermostat, then setting the temperature up to 90 will warm it faster when it's cold, but once it's warmed up the cabin, you set the temperature to something comfortable(say, 70). You don't turn it off, because the climate control system is supposed to be doing that automatically.
