The most sensible thing to do, if its possible, is to see what other drivers are doing first... How a car behaves on ice depends on where the driven wheels are too.
Wise words! If everyone is pirouetting down your street, best leave the car on the drive. The important thing is to try and keep your wheels making traction with the road, so even if you are sliding towards something, it's better to steer the wheels in that direction so you get SOME braking ability rather than to wind on some lock and your wheels slide helplessly. As I found out on a diesel spill, ABS doesn't work when you're going sideways
The fact is, each and every car behaves differently in different conditions, the only general rule for driving on ice is to keep your speed suited to the conditions and avoid harsh use of controls... (isn't that the rule for any conditions though?
)
My last car responded well to the "pull away in 2nd gear" rule, but my current car keeps traction better if you pull away in 1st gear with no throttle, then put it into 2nd, and only apply any throttle once you hit 10mph.
In general, 4wd cars are best/easiest/safest in the snow, followed by front-engined fwd then rwd, because you've got weight over the front wheels. Mid or rear-engined rwd is the worst thing to drive in the snow because the front wheels have no weight over them so don't do much, but the rear wheels have lots of traction so constantly wants to overtake the fronts.
Do you really have no alternative to driving on ice? Can't you take a train, or if your boss is desparate for you to come in, could he approve use of a taxi or hirecar?
