I went back to the original video, and the light is coming from the side almost 90° to the side.. I don’t think it’s a reflection of the pavement. It may be something to do with crash worthiness for pedestrians. A new bumper design?
In the second video, whats with the dark front of the vehicle it doesn’t look like it’s stainless, it looks different than the original prototype. I don’t think it’s a shadow because it moves when the vehicle moves.
