Thought experiment: If they were to damage their vehicle (but assuming it's still legal to drive), who gets to decide whether it should - or indeed must - be repaired? Your parents, or someone else?
(Full disclosure: I recently added some scratches to my wife's car after a concrete pillar jumped out in front of me in an underground car park. I don't need to involve the insurance company, I don't need to talk to any bank or finance company, I can simply go to any local independent provider and have the car repaired. Or indeed not, if I decide it's not worth it.)
This is all true for a leased car as well. The only difference is that when you turn the leased car in at the end of the term, you may get charged by the leasing company for any damages that are currently on the car.
Almost, except that:

Yes, correct, and exactly what I was alluding to: the significant difference between owning and leasing!
EDIT: Maybe I'm missing something (we've only ever owned vehicles outright, never leased). Q: If you are leasing a car and you have a (let's say fairly serious) crash, are you allowed to have it repaired in the manner of your choice, even at a third-party repair shop, and not even be obliged to inform the leasing company about the accident and/or the repairs?
In that regard, ownership is more like "sizing the window in a large enough shape so that all stakeholders are convinced that it will never be required to put special attention on it again, despite ineluctable changes".
Maybe privileges, responsibilities and liability are less delusional terms for that matter.
