My youngest son has a learning difficulty - he has aspergers syndrome - one effect is he does not appreciate danger, and depends very much on routines - disrupt the routine, and suddenly his whole day can be turned on it's head.
He is only 8 years old, but I foresee difficulties should he want to learn to drive, so when we go out, I ask him to identify hazards. Some obvious ones he sees himself, others I point out to him as they occur.
He can already tell you the speed limits, on daul carriageway, and NSL on single, if not lollipopped.
I fully intend to get him behind the wheel as soon as possible, as gears will not be a problem for him. He has already sat on my knee and learned to steer (although not successfully yet!) the car, on a private road.
One effect is I am looking for hazards to show him, even when they are not there to hold his attention, and so pick out things which are not necessarily a hazard, but part of the OBSERVATION part of COAST.
Perhaps If I started things off, you might like to add your own, and we will build up a reference of things others had not considered, such as InGear's "smell of hay" indicating possibility of tractors or hay wagons on the road - perhaps around the next bend.
My own starter is leaves on trees turned back showing a lighter silvery colour - indicating sustained stiff breeze. Watch out for curtain sided wagons lurching sideways as they pass any sort of natural wind breaks.
Over to you all:------
