My mom thinks im going to get raped?

Idk my mom is always scated of me leaving the house past 9 pm. I'm 17 almost 18 and she always uses the excuse that there are creepy people out there that could putt up on a van, throw me in the back and **** me in the ***. She never says this kind of stuff to my other 3 siblings. Is it just because I'm hotter and they're ugly? Honestly I wouldn't mind being raped by a hot girl. I'll be really happy if I got raped by a good looking girl.
