Advice

Okay so I’m 17, my little sister is 15. So, basically she drives the car way more than I do. Like she always gets in the drivers sit so she can drive home when it should be me. I don’t have my license but I’m working on it. She always drives while I barely know how. Like my parents will come o pick us up from school then boom, she’s the one driving home. Or if we go out to eat, boom she’s driving. My parents don’t say anything about her driving us but I should be me, right?What do I do?
