Far as I can tell, the done thing in the industry is to disable all other safety systems (or to not have any in the first place) and to delegate safety entirely to the self-driving AI.

The charitable interpretation of this is that the industry believes that self-driving AI is a safety feature of greater quality than, say, lane assist or auto-breaking.

The less charitable one is that they find it too much work to integrate their AI to other safety systems. Which, to be fair, is really going to be a lot of extra work, on top of developping self-driving.
