Automated driving is advancing in stages. The critical point is not what the vehicle can do, but the moment it hands back control – and the state it finds you in.
The levels of automation
Assistance: the vehicle helps on one axis only – either steering or speed. The driver drives.
Partial automation: steering and speed are handled together, but the driver monitors continuously.
Conditional automation: the vehicle drives itself in defined situations, and the driver must be able to take over on request.
High automation: within its operating domain the vehicle also handles edge cases.
The decisive difference is not comfort but the question: must I monitor continuously or not? As long as the answer is yes, nothing has been delegated.
Taking back control
Between the takeover request and full control there is a span of time that cannot be compressed.

When the system reaches its limits it requests the takeover. This moment is the most delicate in the whole chain: you have to reorient yourself, grasp the situation and then act – and that takes time, all the more the further you had drifted from driving.
Being ready to take over therefore means: staying properly seated, keeping situational awareness, not immersing yourself in another activity. Sleeping, leaving the driving position or becoming absorbed in your phone is incompatible with that readiness.
Responsibility
As long as the driver must monitor or be able to take over, responsibility remains with them. The vehicle executes – the person answers.
This is also why automated functions may only be used within the domain the manufacturer intends: outside it, the system may deactivate without warning.
Remember: automation does not remove responsibility, it shifts the moment of it. The critical point is now the handover.
