As you've said, the Cybertruck may just be the most awesome vehicle conceived, but first impressions are important, and the design is certainly ugly at best. I'm sure some people may disagree with that, but I do think Tesla designed it to be more of a joke, or simply to stand out, though perhaps too much.
The Mini on the other hand, is one of the prettiest cars, with one of the most iconic designs. Absolutely pretty, or cute, whichever is your opinion.
P.S. If Tesla, or Elon Musk is reading this, please oh please, change the Cybertruck's final design. At least put some curves on this 8-bit untextured render.
