It's logical that the manufacturer would bear the liability--assuming the car has been properly maintained, software is current, etc. The driver (passenger really) doesn't have any real agency while the vehicle is driving itself.
It's also a sort of unusual situation in that we can reasonably expect an AI that is a far safer driver than humans will still kill people. That's not a normal expectation for products sold to consumers and used/maintained as directed.
