Clearly the Tesla semi is the real deal as it can be seen in motion several times in this video shot by Bjorn Nyland.

Though Nyland's focus is on the new Tesla Roadster (details here), the Tesla Semi (details here) is caught in motion multiple times during the course of Bjorn's filming.

This leads us to believe that test drives or rides were being conducted last night, though we've yet to stumble upon video proof. For now, the best evidence of the semi being fully functional is found in this video.

If you happen to come across an in-semi video from last night's debut, please share it with us in Comments below.
