It's called Level 4 autonomy. Level 4 ("mind off"): no driver attention is ever required for safety, the driver may safely go to sleep or leave the driver's seat. Self-driving is supported only in limited spatial areas (geofenced) or under special circumstances. Outside of these areas or circumstances, the vehicle must be able to safely abort the trip. Level 5 ("full autonomy"): No human intervention is required at all. Vehicle drives autonomously on all public roads, in all weather conditions, all surfaces, all over the world, year around.
