wherein, the Pre-established Predictive Activation Model was formed pursuant to a classification and regression tree analysis of input data related to the Certain Identifiable Conditions collected from other operators of other vehicles.

3. The method of claim 1,

wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions:

ambient temperature;

temperature set point for an interior of the vehicle;

time of day;

whether the first occupant has requested the vehicle to heat the interior with a blower at a certain blower speed;

temperature of the interior of the vehicle; and

temperature differential between the ambient temperature and the in-vehicle temperature.

4. The method of claim 3,

wherein, the ambient temperature is greater than a certain temperature, and the controller automatically activates the temperature altering element pursuant to the Pre-established Predictive Activation Model as a function of the ambient temperature being greater than the certain temperature and data relating to at least one other of the Certain Identifiable Conditions excluding the ambient temperature.

5. The method of claim 1,

wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions:

whether windshield wipers have been activated;

whether air conditioning has been activated;

temperature set point for an interior of the vehicle;

ambient temperature;

level at which a climate control system in the vehicle is blowing air;

engine speed;

vehicle speed; and

in-vehicle temperature.

6. The method of claim 5,

wherein, windshield wipers are not activated, and the controller automatically activates the temperature altering element pursuant to the Pre-established Predictive Activation Model as a function of data relating to the windshield wipers not being activated and at least one other of the Certain Identifiable Conditions excluding whether windshield wipers have been activated.

7. The method of claim 1,

wherein, the Pre-established Predictive Activation Model establishes rules that are a function of at least the following Certain Identifiable Conditions:

in-vehicle temperature;

ambient temperature;

level at which a climate control system in the vehicle is blowing air;

8. The method of claim 7,

wherein, in-vehicle temperature is greater than a certain temperature, and the controller automatically activates the temperature altering element to impart cooling pursuant to the Pre-established Predictive Activation Model as a function of the in-vehicle temperature being greater than the certain temperature and data relating to at least one other of the Certain Identifiable Conditions excluding in-vehicle temperature.

9. The method of claim 1,

wherein, the Pre-established Predictive Activation Model establishes rules for activation of the temperature altering element to provide cooling and the rules are a function of data related to at least the following Certain Identifiable Conditions:

ambient temperature;

in-vehicle temperature;

whether a rear window defrost has been activated; and

a temperature set point for an interior of the vehicle;

wherein, the ambient temperature is less than a certain temperature and the in-vehicle temperature is greater than another certain temperature; and

wherein, the controller automatically activates the temperature altering element to impart cooling pursuant to the rules of the Pre-established Predictive Activation Model as a function of the ambient temperature being less than the certain temperature, the in-vehicle temperature being greater than the other certain temperature, and data relating to at least one other of the Certain Identifiable Conditions including vehicle speed.

10. The method of claim 1 further comprising:

automatically deactivating the temperature altering element pursuant to the Pre-established Predictive Activation Model, after initially automatically activating the temperature altering element pursuant to the Pre-established Predictive Activation Model, the collected data relating to the Certain Identifiable Conditions collected after initially automatically activating the temperature altering element satisfying the rules of the Pre-established Predictive Activation Model for deactivation of the temperature altering element.
