The front-to-back symmetry is interesting. It may cause some confusion for other drivers, in some limited circumstances, when they can't tell which way the vehicle is facing.

It appears, based on my study of the footage on https://www.youtube.com/watch?v=lIRW8bfy4kE, that it could possibly switch which side is the front and the back by just changing the color of the lights. With RGB LEDs that would be pretty easy to do. But my question is, when would that be useful?

It would be neat that it could pull into a driveway and then leave in "reverse", but that doesn't seem like it'd come up that often for a robotaxi.

The back wheels look like they can steer. That's useful for parking in tight spaces.
