wind will obviously help a vehicle to cool down to closer to ambient temps
faster since it's last been used than
if it hadn't been parked in the wind; but if the same vehicle had been parked
in the sheltered spot for long enough,
it would be the same temp eventually.
in your example, it's just the factor of the wind circulating the air so
that the vehicle reached ambient temps
sooner than if it had been sheltered. the point was that since there isn't any
evaporation involved, it isn't going
to be any *colder* than the ambient temps (as Wind Chill would), and it's not
truly what we call Wind Chill.
cheers!
