I'm so out of context for both of these things, that I really can't.
For me the Nikola video looks like a trailer, or like any typical over-hyped product launche for phones/laptops/gadgets. That it's a vehicle is almost irrelevant.
Also they claim in the youtube video's description that it's a 1000HP semi. And that seems like a very explicit claim. (So if it can't accelerate by itself, then where are those horsepowers. But as I tried to point out in a sibling comment, it's possible they can claim the engine is 1000HP but the fuel cells were not ready. On top of all that I'm very much interested in seeing this get to the courts and hear what they say about what constitutes fraud and what's just run of the mill hype.)
Can you really not differentiate the claims made by Nikola vs a manufacturer building a one-off concept car and parking it at a car show?
