How is it the fault of the mum if she stopped a car in order to get all of the chidren she was looking after across the road safely?

The driver should be more aware of where he was driving and actually look where he is going! I have seen many locals driving like a bat out of hell at my sons school- DESS, and it really angers me to think they do not give a sh*t about children trying to get to and from the car safely!
