You don't much about the law, do you? If I were to damage your automobile, I would be liable for the damages I did. That's all. If I paid for the damages, any civil suit you brought would likely be thrown out, unless you could bear the burden of proof that more remedy was justified.
If you did bring such a suit, you would have to pay a lawyer, whereas I would defend myself pro per. My expense, if you didn't win, would be a tiny fraction of yours. If I did not have a license, that would make no difference to your remedy at all. I would not go to jail. The worst would be a citation for Driving Without a License, and chances are, I would not be cited for that.
If you were to "make a life a living hell", I would sue you and if I kept documentation on your actions, I would win. And even if I didn't, I would have prosecuted the case myself and you would have lots and lots of lawyer fees.
So, let's not make threats we have no idea about how to follow through with, shall we?
