Its really not that bad guys, start to panic when its half way up your car doors and you cant get in or out for that matter.
british winters are really overated, and people just dont have the proper driving skills or sense to deal with adverse road conditions.
i drive all year round and have done all my driving life and have allways managed to deal with the conditons presented to me given the driving equipment i'm in.
half the problem is having the wrong tyres on , you could have 6 wheel drive with diff locks and low range box but with wide & low profile etc summer performance tyres on you are just going nowhere fast.
classic example, take a trip up to our local sainsburys on a day when its been snowing( sleeting to be exact) and there is a few mm on the ground, you can be assured that there will be a heap of 4x4 all stuck , the normal suspect , range rover sports etc/ bmw x?? series etc etc all on silly rubber for the time of year.
in comes a guy in a little old suzuki sj413 jeep on winter tyres and has no probs at all, well to be honest even a lot of 2 wheels drive cars with decent winter tyres get around fine.
just common sense to be honest and a lot of driver just lack that .
you need to adjust to the conditions and that means road condtions and the overall driving condtions around yourself.
