I was talking about this recently with a friend and discovered that we have different opinions, so wanted to find out what other parents of teens think.
Both our DD's (17) passed their driving tests in the spring. I agreed to share my car with DD, as she plays on a sports team, so being able to drive herself to practices is convenient for us both. I also WFH some days so as long as I plan appointments well, I can easily manage without my car. Public transport is dire here, but Uber is available if I need it.
I also let her use the car for socializing, for example, she worked yesterday evening (a summer job at a restaurant) and then drove to a friend's house to stay the night.
I continue to pay the insurance and refill the car when needed. I expect DD to let me know when the tank's getting low and obviously if she doesn't and ends up needing to refill it herself, she'll have to pay for it.
My friend was really surprised that I'm covering all the petrol and insurance. She expects her DD to contribute to both. My reasoning is that DD is actually helping me out by no longer requiring so many lifts!
Now, if my DD causes damage, that's different. I would expect her to contribute to the repair as she is earning and will continue to work at the weekend during the school year.
What do other parents do?
