Snow does something to suburbanite drivers that it doesn't do to city, small town or country drivers, or at least not to the same extent. City drivers drive the same speed in the snow. So do country drivers, only with the four wheel drive on the truck turned on and the possible addition of snow chains. Small town folks slow down about 10 miles per hour, but at least they're not freaking out.
In the suburbs, people drive very fast, almost smash into other cars/posts/trees then slow down almost to a stop, gain their composure and speed up again to the previous dangerous speed.
Yellow lights lose all meaning and green and red lose a lot of theirs.
Here's what went through the mind of one driver moments before his frond end was smashed by another angry driver, "Oh, what are those flashing red lights 2 blocks up ahead? And what are those things across the road that looks like a giant straight candy canes? Oh, what's that? A train? Does that change the rules about what I am supposed to do at this red light? Maybe I should stop on this side of the nifty fat little white line when it is green and then when the light turns red again inch my way out into the middle of the intersection because the big candy canes are being raised up into the air. That must mean it's my turn, right?"
On a side note, where could you possibly be going in Wheaton that you find it necessary to go over the train tracks at a speed that causes your front wheels to leave the ground?
