I'm convinced that Elon made it just because he thought it would be funny. "Let's make a truck that looks like it came out of a 90s low-polygon video game! That'll be hilarious!" He never cared for one moment if it was actually a good product.
The poor people that bought them were the butt of his joke.
No, he legitimately thought it was edgy and cool. He has the taste and desires of a 10 year old.
