Lots of options. Offer cab fare, offer to drive her and pick her up.
It has less to do with the car and more to do with controlling her offspring's life.
She a micro-managing parent, a "curler".
When she was 18, mom didn't want to 'put her out' because she wanted to 'monitor and provide guideance'.

Didn't want daughter to influence son, who if I remember correctly was already drinking and smoking.
