You should have anticipated this and directed airflow to the windshield before you start driving.
I have also never experienced spontaneous fogging of the windshield while I’m driving, and I live in Scandinavian weather which is both humid and cold. It’s always there when I enter the car. The AC dehumidifies the cabin air while driving so it really shouldn’t be fogging the windshield out of the blue while you’re driving.
I have never in my life heard this before. What if the window fogs up and you have to turn the defrost on?
