Why does inside of windshield freeze?

While frost on the outside of a windshield can be caused by rain or snow freezing on the car, frost forming on the inside of your vehicle is caused by too much humidity inside the cabin. When this excessive moisture melts, it can fill the air in your vehicle and then cause frost to form when it sits overnight.

How cold does it have to be for gas to freeze in your car?

Gas with ethanol will freeze lower. I would hazard a guess that for northern-state winter blend gas, going down to -70F (the freezing temperature of octane) is fine. Of course, that’s probably all moot. Gasoline engines don’t start when they get too cold, because the fuel doesn’t vaporize properly.

Why does my windshield freeze at night?

The frost forms because the temperature of the windscreen has dropped below 0°C, and so water vapour in the air touching it condenses then freezes. So the question is, how does the glass get so cold when the air around it is often well above freezing point? The answer is heat loss by radiation.
