Telsas and Polestars are not slow cars, and it sounds like renters are driving them aggressively. I wouldn’t be surprised if torque and speed are also the reason why Tesla is #1 with recent car accidents stats.
I mean, technically you're not supposed to be fiddling with neither radio, AC or other crap on any car, touch or not, when you're driving. All of that should be set before you start driving anywhere. If you follow the law to the letter, the only thing you should operate while driving, is what can be done from the steering wheel controls and voice control.
Of course that's now how most people actually drive their cars...
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.
But besides that, steering wheel control or voice control cab enable/disable this in many cars these days.
