The invisible snow

When winter in Ohio comes, it’s inevitable that you’ll see these idiots that seemingly forget how to drive as soon as a little snow touches the ground.  I’ve gotten used to that.  What I’ll never get used to, and shouldn’t have to; are the people who hear about how it’s going to snow and they immediately drive as if the blizzard is here.
I’m sure you’ve seen these people before. 
It gets cold, the weather man tells us how we’ll get snow; and immediately people drive as if the world is ending.  Why does this happen!?  The snow isn’t here yet, drive like normal!
Almost as bad are the people who start driving as if we have a foot of snow when it’s barely even flurrying.  If the snow isn’t sticking and accumulating, chances are you can continue to drive at your normal pace.
