If your wife refuses to drive a car that you didn't put winter tires on before the first snow, I don't blame her!
Whereas:
My wife will only drive her Tesla in bad weather.
I
responsibly put winter tires on the car before the first snow.
She told me it handled better than the Mercedes AWD SUV she used to own.
We went to a safe place and practiced heavy braking in the rain so she could see her how the car handles in those conditions, specifically with how the anti-lock brakes will be pressing and releasing dozens of times per second which has a "shuddering" feeling underneath you, so you MUST keep your foot planted to the floor and not let off.
If there is any fault here, it is must likely on the preparation of the tires and driver for the conditions than the car itself.
When practically every single reply to you clearly outlined that anti-lock braking feels like a shuddering, and that you should get winter tires on the car, and that your wife shouldn't be on the phone and properly slowing down for the conditions, perhaps there is a pattern.
Hope she can gain confidence in the Tesla, my wife sure has, she drives the Tesla, while I drive a Smart EV.
