Coming to work this morning I came across a soppy bint in an Astra that had cleared no more than a strip 150mm by 300mm from the ice on her windscreen. Not only that she was trying to wipe the fog off the inside with her gloves (or a cloth, couldn't see clearly), crossing the centre line. Needless to say I gave her some main beam and a blast of the horn to alert her to the fact she was in the wrong lane and heading straight towards me.

Then she waves at me like I'm the one doing something stupid
