Hello Allison,
Sorry to read this thread. I teach 'cycling proficiency' to 9-11 year olds here in Yorkshire and I know it TAKES TIME for the children to realise that what they see approaching is a potential danger. We teach them to stop, look and wait. I believe it is a parents job to do what I do....yet I'm thankful for my employment... because we take the time that some parents won't..and hopefully give the children a better chance to recognise dangers when they are 'in traffic'. It's often not until the third session that my colleagues and I see the children actually fully REACTING to the traffic.
The father WILL be devastated. Any motorist who was involved WILL be too - both deserve sympathy. The Father has now learned the hardest lesson. Stay at their side until they are REALLY ABLE to keep the machine controlled and make safe decisions.
I agree with Richard Bridge and SRS - the children are far too young to comprehend ANY DANGER - they are just having FUN - innocently oblivious of the danger they may be in and IT IS the PARENTS RESBONSIBILITY to guard them and inform them of the dangers. The importance of staying close, and doing as they are told.

I know the kids I teach hate me shouting BUT if my voice makes them jump surely that is preferable to a car getting too close....or worse!
Responsibility - it's too important a work to ignore but so few seem prepared to accept 'it' these days.

In sadness, with sympathy and love,
Hazel.
