You're right. All they need now are self-driving electric cars driving and the whole country would be open for easy, self-sustained travel.
Can't wait to hop in my car, or one that I flag down, and it asks me 'Where to?' and I can reasonably say to the 'My girlfriend's house, the liqour store, the cigar shop, and then the beach.' And then recline on the massage couch, play some music, and read.
