I agree NM
Sometimes I think parents are just too busy and forget that there is danger.
Today I was shopping and was just going to reverse but as I looked behind me I saw a women with a trolley. ...it was just luck that I happened to see her 3 y o about 5 feet walking behind her. If I had been a less careful driver her son would have been knocked over.
IMO the mother was totally irresponsible to not have her child under her total control and at the very least have him in her sight while walking in a busy car park.
If I had hurt the child it would have been on my conscience whether I was to blame or not.
