I'm well aware of the market segmentation and where the big ticket items are, thank you very much. Yes, he'll likely get more cybertruck buyers due to fandom but there's a lot of non-truck buyers that are going to rethink giving money to him.
The implication that truck drivers love bipolar douchebags is also vaguely offensive; if that was true the flyover states would be all about Kanye.
