Driving in snow is easy. There's three basic rules:
1. Don't. This is the one most people get wrong.
2. Smoooooth inputs. Braking, accelerating, steering, clutch - anything you control should be done smoothly rather than jerkily. Everything you do needs to gradually load up rather than having all the forces changing directions rapidly. If you put weights on a piece of string gradually, it'll eventually snap, but if you suddenly put a load of weights on it, it'll snap instantly and with less weight on it...
3. Be in the highest gear you can get away with. You don't want the car kangarooing as the engine struggles to suck in enough gas and air because that generates jerkiness, but the higher the gear, the lower the wheel torque and the lower the forces you're trying to smoothly apply for the same speed.
Do that and you shouldn't lose control - though you can hit unexpected bits of ice which might cause a loss of control on one wheel, it should be very brief. If you do actually lose control of the car (which in all probability will be in the form of understeer), just remember to smoothly get rid of some forces - gently backing out of the accelerator or winding a bit of steering angle off will do the job - rather than stamping on the brakes which generates a sudden, excess force (and massive understeer).
Might not help you be like Pentti Airikkala, but it will help you drive the same car in March that you did in November. And always remember rule 1.
If it is possible to adhere to #1 yes.
And to add to Famine's advice...
If you have to drive in snow, you should think and act as if there is a raw egg under your gas and brake pedal. Your objective is to not damage the egg.
1. At least triple your stopping distance.
2. Before you leave the house, think of, and PLAN every thing you need to get done, and every place you have to go. This is one instance when adhering to the all important 7P's might actually save your life as well as time.
3. If you do go off road, STAY WITH THE DAMN CAR!!!
Unless you can see, and safely get to warm shelter, do not leave the car.
Unless you are in imminent danger of being of being struck by oncoming traffic, stay with the car.
4. Since you've planned to be out and about, you have a full tank of gas, so you can run the heater.
5. You have a fully charged cell phone. Call for help while you stay with the car with the heater running.
6. You let someone know when you were leaving and when to expect you back. So if you don't show up they can look for you. And since you've been keeping them updated to your whereabouts they have some idea where to start looking.
7. If you are traveling some distance to work, school, someplace you are going to be all day, carry a "go bag" with you so if you get stranded, you have what you need to spend the night.
Now as far as being a "good" driver--How about I strive to be a better driver each day.
I'm not as good as I
thought I was when I was 17.
But I'm much better than I
actually was when I was 17.
My car control was sublime when I was 17. However, my willingness to take stupid chances was also at an all time high.
