As of yet, AIs are not taking independent actions (arguably unlike the cars). So for now, I think the person using the information would be liable, just like if they copied and pasted information from a site. The individual is responsible for the actions they take, although they may not have the necessary intent to commit certain crimes.
Regarding the cars, it could be argued that the drivers are responsible regardless of the features of the car. But it could also be argued that the features malfunctioned, preventing the driver from safely operating the vehicle. The manufacturer will likely argue thst the driver was operating the car incorrectly, and they will spend millions manufacturing this evidence.
