While the Cybertruck is a screaming gold color, it's for a reason. It's a billboard for the medical spa the Syrian immigrant said he worked hard to build from the ground up three years ago.
There's no billboard on the car in the article. There's likely a small sticker somewhere. This is a common practice by business owners so they can file their personal vehicle as a business expense and dodge some of their tax liability. Frankly it's a pretty shitty practice.
