Icy pavements in Barnet. A solution perhaps?

In Barnet the gritters have been out trying to keep the roads clear (not mine by the way). However they do not seem to have made any attempt to grit or clear the pavements. I have seen lots of people forced to walk in the middle of the road because the pavements were so treacherous. I saw this video of a pavement gritter and thought it seemed such a good idea maybe we ought to have two or three in Barnet. I then found out that these are quite adaptable machines which can be fitted with different attachments for street cleaning as well so can be used year round. It stuck me that if the Townkeepers in Barnet  had access to one of these machines (maybe one between two or three Townkeepers) it might have help keep our pavements a bit clearer.
