ELI5: how do outside temperature readings in cars not be impacted by windchill, engine heat, or being baked by the sun?

I know it’s not linked to a satellite or radio reading as it reads the temperature from the garage and it changes fast once the car is outside.

First, wind actually makes a thermometer more accurate. Windchill is something warm people feel because they want to be warm, and the wind makes the skin closer to air temperature, so we say wind chill because it makes our skin colder. But really wind makes things get closer to air temperature, and get to that temperature faster. For a thermometer, that means wind makes it approach the correct reading quicker, and it also means that nearby heat sources put less error into the thermometer.

With that in mind, car manufacturers put the thermometer in the most windy spot of the car they can find. So yes, the sun bakes it and the engine heats it up, but as soon as you move the wind blows on it, and it quickly changes to the right number.
