Hiring a car to me is a good idea. Staying indoors or just close to home all the time when she is about to leave may not be so good. Does she have a family member or friend with a car or motorbike who can take her for a fee?
Then she is far safer and your helping the family.
One of my wifes cousin was having problems paying the montly payment on his scooter when we were over but needed it for work. So we asked him to courier people about when we had parties and get the ice cream and other items when we ran out.
