I wouldn't want that for my normal commute. However when visiting family it would be nice. "Hey car: start driving towards my in-laws" [sleep] "hey car, find me breakfast someplace" [eat] "hey car, find me something interesting to do" [learn about the swamp spirits] "Hey car, find me something else to do" [learn about railroad that used to run though this little town]. "hey car, find lunch" And so on throughout the day, before letting the car drive another 8 hours while I sleep and waking up in time for breakfast at my in-laws.
