I don't think there's any case there.
GM has nothing to do with all their previous fraud at all. They didn't roll a dead truck down a hill.
And GM legit has the parts they are bringing to the deal. They have battery, motor, and hydrogen tech- and they know how to build a pickup truck. No fraud there.
The whole point of the GM deal appears to be Nikola need supply NOTHING but some CAD drawings (and they DO have those!) and stock (which they also have).... then once GM actually needs to start spending $, they get to bill Nikola for it on a cost PLUS basis.
Hence why I said the deal is win-win for GM. They do nothing but make money on it if it goes anywhere.
If Nikola implodes, that's some bad PR for GM, but that's about it... (and they might still get some $ out of it in the meantime)
