It seems that any review would be focusing on ensuring roads are gritted in a consistent manner, rather than directly improving cyclists' safety which was the point initially raised by Chris Ruane (at least according to the article.) I am, therefore, sceptical that anything truely benificial to cyclists would come of this. However, consistently gritted roads may enable drivers to continue driving in an inappropriate manner with less fear of lossing control when road ice conditions change without warning.
