Earlier today, Musk shared a picture of a herd of Cybertrucks ready to roll off the production line. Look at all those pointy angles…

From that photo, Tom, the truck still looks to me like a CAD file that stalled mid-rendering. But what do I know. As automotive design experts told Aarian earlier, those kinds of flat surfaces are actually quite technically difficult to achieve.

Aside from the whole Elon Musk/Tesla hoopla, there’s a reason why you should care about electric trucks: They’re going to be crucial to transitioning the US, and the world, to planet-friendlier electricity.

A truck, the Ford F-150, is the best selling car in the United States. Rule the electric pickup market, the logic goes, and you rule the future.

Plus, automakers love to make trucks. They have high margins and are more profitable than most other passenger vehicles. Their higher prices make it easier to “hide” the up-front costs of research, development, and, crucially, batteries than with a cheaper sedan or compact.

Cybertrucks have been showing up across the US in recent months. In October, one briefly appeared outside the WIRED office in San Francisco.
