Absolutely! First sign of snow, and I am out in anything with rear-wheel drive. (Once every couple of years here, I'm afraid.) I'd love to know how they define 'unnecessary', though. I've heard people say on the BBC "stay indoors, work from home", as if that was ever an option for most people. Journeys tend to be necessary; that's why we do them. Or do they think we are thinking "Well, it's Storm Force 10 out there, with thunder, heavy rain and travel disruption predicted, so I'll just get in the car and go for a nice relaxing drive", but that a timely warning would bring us to our senses?
