That's just not the case, its a bit like saying you're aware of being blind, but will eventually see. All the training in the world and my boy will never be able to concentrate on moving traffic correctly. His brain is just wired that way, he fixates on goals and targets. His brain filters things differently and excludes information, often vital. Its quite complex, but imagine it a bit like tunnel vision and he can't change that, its permanent. Whilst there are ways to work around it in daily living, it means that safe driving is never going to be an option.
Quite hard to make a condensed reply to this, I agree with what your saying and my original post was probably a little optimistic and as your probably very well aware theres many different levels of autism, aspergers, etc. and very many different progressions such conditions can have through a persons life. I do believe tho that as time goes on a large proportion of people with these conditions do become more aware of and better capable of dealing with the condition - to what degree is also varied. The guy I know from school had massive problems knowing what was and wasn't appropriate behavior as a kid, now approaching 30 he has become much more aware.
