The driver is still fully responsible for whatever happens with the car. So whether the car steered autonomously or the driver turned the wheel it makes little difference from a legal perspective. Perhaps it would just be an aggravating factor that you intentionally let a system that is unable to fully perform the action of driving do this on a public road. Like letting a 6 year old drive.
