With the snow and ice about in UK thought this might be of interest.
Until recently in Winter I carried a set of 'snow nets' in the boot of my BMW Cabriolet. They are effective but require the car to be jacked up to fit them and take up a large part of a limited boot. Even a bigger problem for the Mog.
Last year my brother put me onto these
autosocks . They are quite easy to fit and come in a plastic bag that will fit under the seats. Their performance is very good on snow and hard packed snow and ice.
When I was googling the link above I also came across
these comments. IMO well worth the investment of about £50-60 as they are a potential life saver.
