What about when it hits the windshield, under those same conditions?
Wind will cause an object to lose heat faster ... but will not cool it
below the ambient temperature.
The evaporation of a liquid is a state change whereby energy is used and
heat is given off.
Wind chill is a measurement of rapid cooling of living tissue.

We're going in circles. Stop focusing on the words "wind chill". Focus on
this: Assume you're a chemist, and you know for a fact that you personally
have correctly created windshield washer fluid that doesn't freeze at (to
pick a number) zero F., why does that fluid actually freeze at a higher
temperature, say 5 F., when the vehicle is moving and the fluid hits the
windshield?
Since this phenomenon actually occurs, please base your next response on
that reality. Possible responses:
- "I don't know".
- "Here's why:...."
- "I'm posting a non-answer because I have nothing better to do".
All the above. The answer is blowing in the wind. Actually, it's because
the windshield is cold enough to selectively freeze the H20 content of the
"antifreeze". If you notice ... the wind does not even have to be blowing
in order to freeze a film on the windshield if you use the fluid and wipers
before the defroster starts to warm up the windshield.
I am focusing on wind chill because in your original post you confused wind
chill as being a factor of the temperature of a non-living object. It
isn't.
