Actually I know I'm not - and here's an article to prove it
If you just clear your windscreen then your headlights and indicators are useless and the snow from your roof blows off onto following vehicles.
Where I live about 1 in 5 cars was driving round like this. Some drivers hadn't even cleared the windscreen or side windows of ice. It's unbelievable.
Oh yeah - and there was a thread on this last year and the inconsiderate wankers drivers who can't be bothered to clear their cars properly came up with all sorts of self righteous bollox about how they haven't got time to do it and it's not affecting other people etc.
So.. do you clear your vehicle properly of snow or do you think you're somehow exempt from following simple common-sense measures to help yourself and others drive safely?
