Humans are responsible - not the software
If the autopilot on an airplane goes wrong, it is up to the human to get out of trouble, not the autopilot.
Similarly, the human in the car is in control if something goes wrong.
The responsible human in the car is the person behind the wheel.
My question would be how does the software know that person behind the wheel has a licence and is insured and is in a fit state to be in control?
They have not covered off how the s/w knows it is ok to switch on, never mind where / when.
