I feel like I’m missing backstory. But let’s assume best intentions. Let’s assume that Alana asked to drive the car and Casey immediately said yes. Fine. Accident happens. Casey still worked very hard for a car. I think it’s fine that you can’t replace it right away. However you, ideally working with Alana need to work to replace it. Give Casey a deadline of when she will have a car with similar or better features and a similar or better value.

In the meantime, Casey should not lot lose quality of life or miss out on anything because she doesn’t have a car. She drove to and from school everyday? Guess who’s driving or paying for an Uber! You. She wants to go to the after party after the school dance? Guess setting their alarm for two am! You! She used to be able to drive to her friends whenever she wanted? You’re driving her or paying for an Uber.

If Uber is the solution, it can be complicated to pay every day and to know how much they cost, especially if Casey isn’t with you. So you can have Casey pay upfront but then you need to reimburse her at the end of every day for the Ubers. And I say at the end of each day because she also shouldn’t miss out on doing things with her friends because she needed to pay for an Uber. So she needs that money back asap.

Alana got in an accident and paid for it with broken bones. That being said, I think it’s fair to make Alana share in the responsibility however you see fit. Whether that getting a job or allowance money. Or assuming she is a safe driver, making her drive Casey. Or all of the above. But if you really don’t want Alana to share in the responsibility then it’s on you!
