...https://www.bbc.co.uk/news/uk-scotland-tayside-central-55950942 It amazes me how many people , even if they clear the windows/headlights of snow fail to clear the roof. Once the heat from inside warms the roof the first time they brake all the snow slides forward over the windscreen and they can see fu*k all. Not clearing the bonnet is bad too as bits fly up at speed and hit the windscreen. Alternatively, uncleared snow lies off in chunks and hits the following vehicle, not good if it has part melted and the frozen into chunks of ice. Muppets!!
