I must say I am a bit shocked at the stupidity of people though that are driving in the weather the US is getting at the moment, and I mean driving fast, on highways and so forth. The cold snap in the US is obviously bad enough that it made news here, showing a fed ex semi, 40+ tonne of truck, lost control on a straight highway because of ice, going quite fast, sideways cleaning up all the cars in its path.
Now wouldn't commonsense prevail, and if its that icy and snow ridden across the US, stay of the roads and allow the weather to calm. Mail can wait, I'm sure of it. How many lives are being lost because of this weather in the US? No doubt quite a few.... why aren't chains compulsary to use on all vehicles in this type of weather? I know they are here in Australia in the snowy mountains and skiing areas. Your allowed to go so far, then stopped to ensure your chains are on... depending obviously on the road conditions. Each person is brief at a checkpoint on the conditions they are about to go into, and if bad enough, nobody gets through.
Car at slow speed is one thing I guess, a semi trailer demolishing cars, thats a bit sad for those who are on the receiving end of the truck. Damn...
