Snow-one Remember's Where the Lanes Are?

Why is it when it snows, no one can remember where the lanes are?

I swear, everytime it snows more than a dusting, everyone who drives these roads everyday, forgets where the lanes actually are.
There's an intersection in town where there are 3 lanes: one for turning left, one for going straight, and one for turning right. Today, half the ppl seem to have forgotten that there are seperate lanes for going left and straight. Actually, someone forgot yesterday too and mistook the left turning lane for going straight and cut off a few drivers.
Another street in town, there are two lanes in each direction. When it snows, everyone forgets that there are two lanes and start out in one lane and eventually drift off into the second lane about halfway down the street. I typically use the second less travelled lane to pass ppl who are going to slow. In the winter, I usually can't do that since there ends up being only two very wide lanes on the four lane road.


Another thing that bothers me in the winter is business owners who shovel all their snow onto the road. When they shovel it into a driving lane, its a pain in the ass for drivers in smaller vehicles to try and maneuver within that lane. When they shovel it into a parking lane, good luck getting out of it if you even in!
