Windows data detects the percentage that any given window is open. By using sensors on the vehicle, windows data can be transmitted remotely via mobile data networks to inform users of the status of the vehicle's windows. There can also be a simple open or closed position data point captured as part of windows data, this depends on how well the vehicle is equipped with sensors.

Drivers may not be present when windows are open and it starts to rain. Remotely accessing windows data can not only view the status of the windows, but it can also allow for remote shutting of windows to prevent a wet interior.

In contrast, on a hot day, having open windows protects contents such as pets and children. A cool airflow is required when a vehicle is stationary. Windows data is used to make sure the interior temperature is manageable.
