The current vehicles sure seem to come close. I'm not entirely clear on how they've missed this goal, but the current models can do full self driving where I live, including parking.
Sure they have improved but how do we define success? Is success "It can drive a road it has never been on?" Even then I'm not sure because the model (not the physical car) has probably scanned that road before so it is recalling a prior route while being aware of hazards. Is that learning, or rote memorization?
