> Which definition of "good" do you want near you when there's 3" of snow on the road?
When there is snow on the road you should not be near either of them.
You should be far enough behind that you can stop when the car in front gets into difficulties. The rule of thumb on a dry road is that you should be three seconds behind. At 100 km/h (about 60 mph) that's 83 m (about 270 ft), say 17 car lengths (for my Tesla S that is). If there is snow on the road perhaps it would be wise to allow more distance.
