One of the issues with autism is lower ability to recognize and communicate own emotions and needs. Other people do not get direct straightforward information, they get less information, because autistic himself/herself have no idea. One of very typical results is very emotional autistic person who will insist they are totally rational and non emotional in the moment. It can also cause autistic to have lower emotional control, because emotions are harder to control when you do not understand them.

Autistic are not collaborative - they frequently end up locked in own heads completely ignoring what other people openly directly say.
