I did think it was imminent at one point, but the fact the delivery date keeps pushing out shows its far from complete, and is only usable in controlled circumstances. I use it in traffic jams, or motorway driving, and that's it, anywhere else and it's just asking for trouble. It's useful in those limited cases, but it's a shame how many false promises have been issued, I've a lot of respect for what Elon has done, but he's really oversold this
