Winter Driving Tips

OK, so there's no snow in the forecast right now, but I came across this (on the SLOG) and felt you wouldn't want to miss it. It's a KING 5 broadcast of a very icy Portland.

The slow motion ballet of cars on ice is riveting, but the pedestrians standing around watching the sliding cars are most perplexing: momentum (p) is still mass (m) times velocity (v), even if it's cold outside. v is very low here but the m of the cars is still thousands of pounds and p could do a number on anyone's limbs! Thank goodness it didn't.
