Actually, if its quiet I suggest going out and having a practise, I'm not suggesting that you go mad, or put anyone in danger, but if you are nervous (and understandably so) about driving on ice then doing it under controlled circumstances to learn about countersteering and back end drift when you are sliding will actually make you a safer driver in bad conditions.
I was very lucky in hindsight to have spent 10 yrs on a motorbike every day summer and winter and I can honestly say I don't feel nervous driving my car in the snow.
Also any time you do go out in icy weather make sure you have your mobile on you, a blanket, shovel and flask of coffee, just in case you do get stuck.
