I watched a few videos of the channel. I'll link it here for the others, it's some damn great resource, this couple is doing some amazing public service.

And it kind of confirms what I suspected - I'm not autistic, just raised by one (my mum). For example, this video shows it rather well for me:

I'm not exactly sociable, but I don't really struggle with group collab or social situations.
I'm actually quick to get implicatures (implied meaning).
If anything, people complain my eye contact is "piercing" - I tend to make a lot of eye contact while speaking.
I'm not really annoyed by changes in routine, interruptions, or multi-step tasks.
etc.

I do get pissed at being misunderstood, but I believe this is common for all people; nobody likes it, but I think for autists this might be specially aggravating because they get misunderstood far more often.
