I'm a bit more skeptical of Byton than Rivian, but they are also releasing their prototypes to the public at the LA Auto Show this week.
Here is the first review I've seen of the car.

It will be interesting to see how the public reacts to such a concept. The massive screen has always baffled me. I thought they would lose it as they moved forward but it is still there in the design being shown today.
