If you can hold the owner of a car liable for a crash then what stops you from holding the creator of a car liable for a crash? Why not go after Toyota? By this line of reasoning Toyota is just as culpable as Ms. Fong.
Indeed, some tort actions have gone beyond owners and even pursued manufactures -- particularly gun manufactures.
The idea that an object owner or object creator might be liable for the actions of an object user is unreasonable and perverse. It has a chilling effect on innovation and forces small businesses (who can't afford to lobby regulatory protections such as the Graves amendment) out of the market.
