I was trying to say I don't believe that autistics are better than others at navigating their
physical environment. I suspect that it's the *dynamic* environment -both social and otherwise- that autistic brains struggle to process, which could leave them with more time to work on the *static* environment (if such can be said to exist on a Buddhist forum

- well, you know what I mean

).
For example, although I've never had the typical autistic problem with traffic (shared with other animals to judge by typical roadkill, it seems

), I remember first perceiving *moving* traffic (rather than a series of still images successively jumping forward as in old stop-motion animation) at the age of 18, though by that time shortsightedness was developing anyway - While I still had '20-20 vision', my brain was so full with
every tiny detail of what I saw that there just wasn't room for fancy stuff like movement or facial micro-expressions
I mention this because, as I mentioned elsewhere, I was recently surprised to hear that 'building up a mental picture' is often used as a metaphor for visual perception - For me, it feels more like 'all the details all at once'. It's almost the opposite of a normal sensory disability like blindness.
I've had more time to post recently, as I've had to stop working for a bit (owing to the complications of a brain tumour removal op). However, I think Music has already answered your original question as best as any 'aspie' can; that might be why he hasn't replied again.
