I feel like the vehicle apology is convaluted, especially when you consider GM, and John Deer, vs. the owners.
I both own-as-in-sole-possession-of and own-as-in-responsible-for my laptop.
It's mine, and that is a good thing.
So I can sue you if you spread malware to my computer? That's what "own-as-in-responsible-for" means.
You can certainly try.
If I am unsuccessful, then you are not really responsible for your computer, are you?
If you are unsuccessful, I have a better legal defense than your offense, that doesn't change who is responsible. The burden of proof would be on you.
