My friend has taken contraceptive pills on 8 sept and she was expecting her periods on 30 sept but instead of good flow she is only having spotting. My exgirlfriend is on my car insurance. She has her own car. I was going to leave her on it until she is 25 (Feb) just to be nice, I guess. I saw a friend of hers driving her car. If she lets someone borrow her car and something happens, can anything fall back on me in anyway?
