Doesn't matter if its an accident or not. Not being intentional just means there's no criminal mind behind it. You still caused damage to someone's property and you should have to pay the damages. This is why we have car insurance.
I would be pissed off if some kid just ran into my car and then drove off because I'd have to pay to fix my car because he did something stupid.
No offense (again) but Jesus said to not exact evil for evil and to turn the other cheek. Being a Catholic, this is just what I would do (not demand reimbursement).
