I really cannot fathom this out. Why is snow so different now to what it used to be in London and elsewhere? Why the total disruption everywhere? why the major news item for 36 hours and still trickling on? "There is snow...look". 
It used to snow every winter, yes it really did snow. Gloves hat, coat, scarves suitable footwear and knee high socks, for outer wear, and warm layers under the coats. Boys wore short trousers and girls wore skirts or gymslips. We took our toboggan to the local park and whizzed down the 'nursery slopes', then a multiplicity of times, drag the sledge up the slope to repeat the exercise.
We played snowballs before and after school. The various snowmen we constructed were smashing. There weren't too many carrots but there were smidgins of coal for eyes, also the loan of a scarf or hat till the owner went indoors. We'd rush out the next morning to see if our snowman was still there, or needed a bit of a re-structuring. We took a delight in adding to it, making the snowman rounder and fatter. 
Schools didn't close. We attended, so did staff. Public transport ran. Personal transport was not so much in abundance, though it did exist. (We had to cross roads carefully). I can remember ice lying on some London roads and not melting till late April or early May.
There were no gritters, salt sprayers or snow ploughs in London then, yet neither did London and its transport come to a halt. The severe winter of 1962/63 did not create the kerfuffle there has been this week. We functioned.
Scotland, takes measures to keep working though it is not always possible to keep every little village and hamlet clear. Main roads are not blocked for long if they do get affected by major snowfalls. Efforts are made to keep lifeline transport flowing at some level. There have been severe blockages from time to time on far north roads, which by the panic levels of news we hear and see, would totally freeze up the functioning of our neighbours for a long time. Not here, hardship because of weather, is kept to a minimum, and life goes on.

Good points. In Norwich the unemployed were set to work chipping the ice off the pavements, so the City was rapidly cleared of hazards.
