My wife and I find that Mondeo’s heated windscreen is extremely distracting when driving in the dark
Depends on the screen, the OEM one in my focus was barely visible, the replacement from autoglass is much thicker wire (and seems to be shinier copper too, the old one was a dull red). The new screen also seems to have a bit of a lens distortion effect, can’t put my finger on it, but everything looks subtly different.
I thought it was warm air that can capture more moisture (hence massive tropical rainstorms) but opening windows to let cold air in (being drier as it can’t hold moisture) helps as it replaces the relatively warmer / wetter air inside????
Absolute Vs relative humidity.
Warm air is generally wetter as it has more capacity. So when they say 90% humidity that means the air is holding 90% of it’s capacity. But when you cool it the capacity drops but the absolute humidity remains the same so the RH goes up.
Until you get condensation, that’s how Air Con works, and dehumidifiers, blow warm air over a cold plate and all the water condenses, then blow it back over the hot plate to return it to the desired temperature.
So if you want to dry something out, put the air con and the heating on at the same time.
Same reason your skin dries out in winter, you’re sat in a room with the heating on the same temperature as it is in summer, but the absolute humidity is still the same as it is outside where it’s 0C (unless you live in a very well sealed house).
