Understanding the limits of your vehicle, understanding and experience in different weather conditions, situation awareness and defensive driving are worth IMHO worth much more than winter tyres, ABS etc.
When I used to ride bikes in snow and ice, it was always back wheel braking, you can fish tail down the road but lose the front end and you knew you were going to be dumped in the road. Today I was round my neighbours when the news was on and watching the muppets trying to drive in the snow was comical and also depressing. They don't understand rolling friction is much less than static friction.
So start off gently in a high gear, if on a hill without LSD a small amount of handbrake on a RWD car can help etc. In wet and slippery conditions fast driving is all about smooth driving to keep static friction in charge.
Maybe after a few winters in The Ukraine, you'll think differently. Yes, awareness, understanding your vehicle and driving appropriately are all critical - I am never arguing against that - but if summer tyres don't grip, they don't grip. It's as simple as that. I have had many experiences in FWD and RWD, summer tyres, winter tyres, fresh snow, slush .......... and know the differences.
After snow here, people generally don't potter along at 15mph on a motorway. No, they don't do 80mph either, but life does carry on. No big dramas, hours and hours of news reel about the weather etc.
As said in a previous post, how do the Danes, Swedes, Norwegians etc carry on?
