Child Deaths from Traffic Accidents under 16 years of age 2011 - 60 http://makingthelink.net/child-deaths-road-traffic-accidents
Wow! That (if correct) is incredibly low, suggesting the UK's drivers are, in general, very careful around schools and urban areas. Yet the OP wants to compare a driver who makes an error to a "kiddy fiddler"? Even more incredible.
When driver demonisation threads pop up I always think of Dr Thomas Munch-Petersen who lost control of his car after dropping a mint, killing 3 people. He pleaded guilty and was jailed. One of the victims mother's said this:-
"My family and I feel that to send Mr Petersen to prison would serve no purpose at all. This man and his family have suffered enough. Lives have been broken without further adding to the tally.Throughout life, we all make mistakes. Most pass without future incident. A few have tragic results."
