No because you are still not removing any heat. The wind doesn't make ice any colder

But wet bulb temperature takes account of moving air doers it not therefore if the sensor is damp wind will have a chilling effect? Or is it that human skin feels a lower temperature due to evaporation and wind carrying out surface moisture but of course a temp sensor cannot 'feel'...???

Tell that to the penguins!
If I remember my 'O' Level Physics, it's due to Latent Heat of Evaporation, and is the principal used in refridgerators.
It's why a simple fan cools you down on a hot day (remember them?) even while the air is hot that you are wafting over yourself.
I agree. A lie down is in order.

I usually disconnect my starter battery if I leave the van un-used for any time. So the dash clock is never the right time.
This little clock plugs into the cig lighter and has a back-up internal battery to keep it going when the 12V power is off.
The other useful thing about it is that it gives you a battery charge (voltage) reading, plus inside / outside temperature.
I have no idea how accurate these readings are, but for the price I am not too worried

Update = Well in my opinion, more Chinese carp as I suspected.
The Voltmeter on mine reads about .8 of a Volt low

The outside temp sensor reads all over the place. I suspect this is due to moisture on the unsealed contacts in the sensor (I might try and seal it)
The "icy road" alarm is a damn nuisance as you cannot turn it off. Even worse when I had the unit wired permanently on, it woke me up at 4am one night!
The "icy road" alarm actually stopped working recently. Good news or bad ? At least it won't pee me off on a long journey at minus temps outside.
The clock re-sets itself to 12:00 whenever the inside of the van gets very cold (most nights recently)
So all in all not worth the effort of fitting it
