Just an observation from somewhere were it is compulsory to have winter tyres fitted for about 3 months of the year if you want you insurance to play ball, I have seen three vehicles today parked at unusual angles in the local fields. Admittedly they are not blocking the roads in any way but that is mainly due to the fact that all the roads around here are raised above the field levels and have no hedges just ditches as boundaries.
The autobahns are clear, albeit with reduced carriageway widths, local throughways are likewise. Village roads and interconnecting lanes are only tractor scraped in the main and snow tyres are essential. And people here like anyone with any sense refrain from driving on the local roads unless essential.
Better prepared? Yes, cost effectiveness of preparations, Yes, because it is a known condition Every Year.
A spare set of wheels and snow tyres are at least half UK prices, due to quantity sold I suspect, but if I had them at home in a very hilly part of the Cotswolds they would have been an advantage to me on no more than 4-5 days in the last 20 years if my memory serves me correctly.
Our village when hit by significant snow, (not every year), is within 1/2 a day, no worse and from what I can see at the moment perhaps better cleared than here.
