I think what also contributed to the commercial failure is that it actually looked great at the early prototype stage, but the production car turned out to be uglier. Most people don't notice this, but they feel it subconsciously.

Go find early pre-production Cybertruck photos and compare with the actual prod car. It became subtly bulkier, uglier, less streamlined, and IRL it looks even worse than on the photos. Probably they had to do this due to production difficulties or to meet some standards, or to cut costs, whatever. But it was a mistake.
