You can make that argument. At the same time, Tesla needs some splash to get attention, especially considering that they don't spend (waste?) money on advertising. They didn't need to make Plaid-but how much media attention has that gotten as (one of) the quickest (0-60) car in the world? How many people remember the 4-door family sedan dusting half million dollar supercars at the dragstrip? How many magazine/social media articles have been written about it? And on the street-how many remember getting dusted by one? Regarding the X-most people would only remember it as a crossover EV without the "falcon-wing" doors. Those doors (and Plaid) both showed Tesla's engineering stones and willingness to "boldly go where no man has gone before". Granted I think they underestimated the actual problems posed by those doors but it made a spash and got some attention. How many still remember the "gull wing Mercedes" that otherwise wouldn't have a clue of it's existence?
IMO the Cybertruck will be the same way. You can see a Lightning on the road and not even notice, it's just a rebuilt F-150 as far as anyone is concerned. Same with Silverado EV (assuming they actually get them on the road)-it looks like any other pickup from the last 70 years. Not worth noticing. Cybertruck...will be noticed. Some will love it, some will hate it-but it will be noticed. IMO, if Tesla can deliver on the promises and performance, and especially approach price parity with an ICE P/U, I think it will be huge for the company.
