Gary I feel your pain. I grew up in N Central Indiana and then lived for 5 years in N. Indiana is a "lake effect snow region". I have all kinds of snow driving experience.
I now live in Southern Indiana where if it snows an inch people freak out. No one has the proper tires, nor do they have any clue how to drive in the stuff. I feel like I take may life into my own hands everytime it snows. The worst offenders are usually those with the SUV's who feel "this justifies why they have 4 wheel drive" however, they are usually equiped with "all season" tires at best. It amazes me how people drive. The thing is going too slow is just as dangerous. A typical southern Indiana driver well drive along and reach a bridge or overpass, their brain will say...these freeze quickly....then their reaction is ....slow down.....apply brakes....result slipping, sliding and losing control as everyone else starts the tail light dance. Note those drivers....don't brake...release the accelerator and coast, you will not lose control.
I have a confession....I get perverse joy out of seeing an SUV fly by me on the highway to only see them in the ditch a few miles down the road, all the while I cruise along in my rear wheel drive car with dedicated winter tires and never get stuck nor have any true sliding problems.
