Even full autonomy, but restricted to very limited intervals could make sense as a compromise. E.g. up to five minutes of hands-off (and eyes off) per hour or something like that. It looks weird at first, because hey, if the car can drive itself for five minutes, why can't it drive itself for five hours? But only at first glance. I believe that it makes a lot of difference which is the regular case and which is the exceptional. Humans would be terrible at idling most of the time to occasionally take over, but computers can be just as attentive waiting to take over as while actually driving. Also, that time-limited "hold the wheel" mode would typically be engaged exactly for those times when the human driver is not at their best (tempted by communication devices, tempted by the food basket or just wrestling with navigation), so achieving better than human would be relatively easy.
