I had to take my wife to her work this morning, despite the Red Warning and blizzard conditions. She works in the local hospital and they are desperate for staff. I managed reasonably well. Just kept it in 2nd for most of the journey and, despite my summer tyres, it just plodded along. As I returned home there was a bit more traffic, and a couple of cars were already stuck. By 8 am it will be gridlock. Personally, I think how you drive in snow is much more important than if you have summer or winter tyres on. The road I live on is a gentle incline, nothing really to speak of, but there was an Audi A3 with its engine revving and its wheels spinning as I came past.
I did have one problem though. As I tried to reverse back into the garage, the up and over metal door was caught in the gale force wind, and came down onto the back/roof of the car. I'll have to wait until it is daylight to check the damage, but at least the glass is intact. Think the problem was due to snow and ice on the bottom edge of the door, upsetting the balance.
