Ren, personally I don't think its practical to include it, or not. Its one of those things thats unsolvable IMO. SOME auties/aspies would be a danger on the roads, some wouldn't. But actually assessing it in any way beyond the driving test with instructors and practice sessions, would just make it massively more difficult, and probably more expensive for those on the spectrum to drive than it would be for NTs. There is no ideal solution, there is only the practical one 'no it shouldn't', well, yes it should but it can't be made to without fucking things up altogether so we are going to have to ignore it'
Not exactly elegant, but it'll have to work. And just be hammered into shape if it gets a few dents here and there.
