ELI5: How can the thermometer on a car give the temperature without being affected by wind from driving?

Wind chill is specific to humans and animals trying to maintain body temperature.  It doesn't actually mean the temperature is lower, only that you feel as cold as if the temperature were that low in still air.  This is because moving air carries heat away more effectively than still air.  So thermometers are not affected by wind chill.

In fact there's an opposing effect that very fast vehicles (we're talking Concordes and SR71s here) whereby moving very quickly through air causes you to heat up.  Cars aren't fast enough for this to be a noticeable effect.

In fact moving air helps car temperatures be more accurate.  A car sitting in the hot sun will show a temperature that's substantially higher than the surrounding air temperature but, once you start driving along for a few minutes, the moving air will make the car thermometer accurate again.
