How come most autistic people doesn’t see the things we see?

I’m not trying to offend or criticize them but what’s they’re deal?

I have a cousin who is 16 years old. She is autistic, very intelligent, does well in school and can greet you, BUT she is very clueless. To put it bluntly, she’s very naive, and she really sucks at social cues setting most people off. She hates when people treat her differently but what did she expect? She’s autistic and she’s special needs. Also she believes that everyone loves her and will be sweet and nice to her because she’s “special”. She expects people to be kind and nice, but she isn’t always nice herself. I’ve seen her nasty attitude but she’s a teenager. All teens go though it. Anyways she’s going to a public high school next year and my uncle (her dad) has been warning her about how public school isn’t like the private school she has been attending and not everyone is going to be friendly or like her. She knows that not everyone will like her but she refuses to believe it.
Even my brother and I (her cousins) even tried to tell her that public school isn’t all bad but just be aware of snakes and bullies. She better listen to her dad because he’s telling facts. It’s so frustrating that she doesn’t listen!! She has this mindset that the world will be a loving place and people will accommodate her and treat her so nice. Um NO they won’t! And we’ve told her! Plus she’s a spoiled brat. Sometimes my uncle doesn’t really punish her and plus she throws horrific temper tantrum and she’s a big girl. I mean BIG. Like I think she’s 6ft and heavy set. Her dad doesn’t let her push her around and yells at her to knock it off. She thinks everyone is her friend and doesn’t see the red flags. She knows right from wrong so she won’t do everything they say. I can see why her dad doesn’t let her go places by herself. How can I get my cousin to wake up and face reality?
