 While there are autistic people who are more easy to identify like Peridot, there are people like Pearl who you wouldn't know unless they told you. I actually fall into the Pearl category in this case since a lot of my traits aren't very pronounced or visible. Usually if, and when I tell people, I'm usually met with a lot of disbelief and bewildered looks. If anything, I guess it really only proves my point that people don't really know a lot about this subject.
