A few years ago now I was joining the M40 going south at the A34 junction. I was on the slip road, right hand lane having just overtake a 40ft articulated lorry, when a 3-Series BM pulled into the left-hand lane from behind me, undertook me and proceeded to joint the motorway in front of me, cutting across the whole carriageway straight into the outside lane. Now this was crazy in itself, but the woman in the BA stewardesses uniform in the driving seat was putting her f*cking makeup on using the rear view mirror.
