The look is due to the function.
Cybertruck was designed to not need a body stamping plant or paint booth. Both are hugely expensive, take up a lot of manufacturing floor space, use a lot of material and energy. Simply take a roll of stainless steel, cut out panels and fold along straight lines is a brake. Designed to not easily scratch and capable of going off road, in narrow lanes without finish damage. Able to take significant impacts without damage and be inexpensive, simple and quick to replace panels. Painting of bodies is hugely expensive and environmentally a disaster. Takes a ton of energy to filter out all the paint contaminates from the water walls. People do not need to run paint guns, wearing environmental bunny suits or employ expensive and hard to maintain paint robots.
The look is different. The beauty is in the functionality of the design.
And all of this is just false. As it turns out, it's more expensive to make . Owners are spending another $5k-$10k to wrap it in order to hide fingerprints or discolored Stainless Steel. Wreck after Wreck has shown this thing falling apart and being totaled. A Subaru Outback is off road capable, nothing special.
It's essentially a You Tube Car.
