Input: OK SO BACKSTORY: I just got my drivers license a week ago and I really like using it. So my sister left for college and she is back for Thanksgiving break. When she left I inherited the car from her but its technically our car. My mom is at home and my Dad is retired so that means we have an extra 2 cars she could drive that I'm not comfortable driving. 
She told me she needed to run some errands today and asked if she could specifically use our car, she is a much better driver than me and is capable in driving the other 2 cars. So I told her that she could use the car in the morning but when I need to leave for school I need the car, she offered to drop me off but that takes away my ability to chose when I leave school, and I normally like to stay after and talk with friends. So basically I ended up telling her that she could use my Moms car (which is far nicer than our car) and she ended up grudgingly taking my offer, but declaring she gets the car for any other times she comes back. So AITA for not giving her the car?

not lending my sister our car
