Large established companies would be legally cautious on things like fake battery swap stations (couldn't operate with real road wear, just taken from the battery install tooling in the factiry) to claim hundreds of millions in subsidies, or using NASA money to buy junk bonds in another company he had interest in (SolarCity), then giving a presentation with faked shingles to bail out the company through a merger and prevent the bonds backed by NASA money from failing and the repercussions from that. Then use SpaceX to create Boring Company without giving them a stake while Musk got 90% (later reversed in a quiet settlement giving SpaceX around 6%).
You really shoehorned that one in there. An established company wouldn't have to do all that, they could have just made and electric car and/or re-usable rockets.
