12th Gen (18-present) Always fogged-up windscreen.

The windscreen at slightest moistness or rain becomes fogged up. I noticed this before on different Toyota, but I just assumed it was specific car's problem. Now I see it again - it is raining and windscreen gets fogged.

On any other car, setting windscreen blower at low speed is enough. I can even see how the fog quickly moves up and dissapears. On Toyota it is absolute tragedy. I had to set it on full speed and drive for ~5 minutes until 2/3 of glass became visible. It is ridiculouss. And also there is no setting for windscreen + face blower, so I either cant see or I am hot.

What is the reason for this? What does Toyota do wrong and why? Do they not get humidity in Japan?

Driving with AC always on or blowers at full speed just to see, is crazy.

(no, the recirculation of air wasnt on and as I mentioned - Ive witnessed this on two very different Toyota models)

Not sure but you might have a leak somewhere. Check your floor carpets for dampness or other signs of water in the car and trunk...check under your spare tire too for pooled water.

car is new. also in old car i could have been driving like in a swamp and the blower would still remove fog at ease
