How can I set boundaries with an overbearing mother while living at home?

I’m an adult and unfortunately I’m still living at home. I want to move out but everything is expensive. Sometimes I feel like my mother is glued to my hip. She still treats me like I’m a child. There are times where she insists on taking to places I can go alone. Even though I can drive myself like to the store. Perfect example, I’m waiting for her today to go to early voting when I wanted to go during the week to avoid the lines. If I don’t wait she’ll guilt trip me making me feel bad.
