I think it's a little harsh for this driver to be voted the worse driver for March so far. Of course the Audi driver should have stopped and given way to the right at the roundabout and if it had happened on a driving test he/she would have failed (and rightly so). Having said that, it wasn't THAT close to a collision and I've seen much closer near misses on roundabouts and junctions. And the Audi driver did flash the hazard lights to apologise so at least they acknowledged they were at fault, which suggests they have learnt from their mistake which is a good sign. To me it was an error of judgement and a mistake rather than dangerous/careless driving which is more deserving of "worse driver of the month" than this Audi driver.
Maybe blur out the child's details? I think she doesn't need to be reminded of it especially as it was none of her doing? Just sayin.
