I used to be but after the last few years when Britain has had more snow than usual (for us it seems like loads but to people who get proper amounts of snow it's nothing ) I've got more used to it. Thankfully I've never had anything bad happen in snow *touch wood*

I still get nervous though driving in situations where I have had an accident in the past. The memory does play on you, and of course the worse the incident was the worse the fear is
