I was driving into town today behind a car that had a sign on the rear windscreen saying 'Autistic Person'. There was some more words on it but it was too small to read.
I've never seen a sign like his before, and have virtually no experience of autism so please excuse my ignorance but could anybody explain what this sign is for? Like the 'baby on board' signs are intended to discourage d*head driving, does this have a similar purpose?
