I really don't follow autonomous cars all that closely, is Zoox still the only one that is designed to not have a driver in terms of the actual car? I remember seeing it like maybe 3-4 years ago and noticing that it had 4 wheel steering and being pretty impressed in terms of how it could behave in tight spaces. Of course AFAIK actual autonomous driving is nowhere near solved so this is probably still some years away.
