Actually, I've seen answers to all of those questions.
> If I own a self driving car, is my insurance insuring the AI as the driver?
Yes. Google has stated they will assume liability. Other companies pursuing this say the same.
> Is the driving record of that AI individual to my car, or to AI's of that software version ?
This one is actually easier. The insurance industry will have much better figures on the probability of having a claim to pay for the AI drivers, since all those drivers will drive the 'same'. They will be able to say that cars of model X get into
> Can I sue the AI, or am I suing the AI manufacturer. Is the AI the car, or separate from the car?
The manufacturer gets sued. The manufacturer would keep insurance and lawyers for these lawsuits.
> am I suing Google or Ford ?
You sue whoever sold you the car. One throat to choke.
