Okay on the M6 at the weekend, travelling at 'reasonable' velocity. (Would be points on my licence not a number of breakfasts at Her Majesty's pleasure) Some dirty crep on the windscreen, I wash-wipe...... Wipers go feckin crazy, arms mix up and the driver side went under passenger, (It's off to the hard shoulder for us, yes they were aero spec). VW dealer has reset the arms this morning. I notice the scratches on the screen, nothing major but in the sunset going home tonight, pissang me off. Can autoglass miracle something up.
