Wind speed has almost no effect on a sealed vehicle and is not factored in unless the
Ventilation toggle is enabled. For cars, the figure represents the cabin temperature after
roughly 45–60 minutes of parking. For motorhomes and caravans, the model allows for lower
heat gain, slower response from insulated panels, and retained occupied-space warmth, so
