 You may have a big liability issue when you reach the highest level automation, not before, but then taking the pragmatic approach in road safety and in road crash investigation, most likely the principles will have to be followed, but are followed in aviation. In aviation, you have an investigation which investigates everybody, not only the captain of the aircraft, but everybody. So maybe that's the future, but let's not run ahead. Definitely this is the big issue and it is not yet solved.
