This is not directed at anyone in particular, but here is my advice.
Stay off the roads when you don't need to be on them so that people that do know how to handle the conditions can actually get somewhere.
[rant]We have a snowstorm two years ago and got about 10-14" of snow. First time in many years we got that much at once. My wife drives a 4wd pickup. We both stayed home from work becuase it would have been pointless to be there without many others who could not make it. I drove to my sister's house to borrow her big snowblower. I could not pass her street because soe lady in a Civic (bone stock, but it is a low clearance vehicle) was stuck right in the middle. A neighbor was kindly helping her dig out the snow underneath her car. I told him to stop whiile I drive around her so I could get a tow strap. I proceded slowly and got hung up myself. Not bad as I backed out. Then told them to stand aside so I could get a little speed. Both of these people warned me about possible damaging this brance new Civi. I told them my truck cost $35k and I am more concerned about it her little car. For my own sake, I am not going to do anything stupid. So, I went by, got the rope, pull the car out and told the lady to park the car for the day. Why was she going out? Shopping at the mall.
To those AWD and 4WD haters, just try driving one such vehicle for once. Same with dedicated snow tires. Many all terrain tires used on trucks and SUV's perform very well in the snow compared to typical passenger all-season tires. Just because you are driving white knuckled doesn't mean everyone is. So, get out of the way; I'm coming.[/rant]
