Cybertruck Sales Are Dead in the Water

futurism.com Unknown 2025-07-20 01:27:34

Just when you thought things couldn't get any worse for Tesla's Cybertruck, sales for the controversial pickup truck are circling the drain after dropping off a cliff. In numbers, the Elon Musk-owned automaker sold just 4,306 Cybertrucks in the second quarter of 2025, according to the latest data from Cox Automotive's Kelley Blue Book — a stunning 50.8 percent nosedive from the same period last year. It's also a big dip from the quarter before, when Tesla eked out a barely more respectable 6,4

We keep talking about Cyberpunk 2077 five years after launch for good reason. It’s still a high watermark for in-game graphics. I’ve been playing it religiously for the fifth time on Switch 2, amazed that the game runs so well on a slim handheld.

It’s hard work soaking up sunlight to generate clean electricity. After about 25 to 30 years, solar panels wear out. Over the years, heating and cooling cycles stress the materials. Small cracks develop, precipitation corrodes the frame and layers of materials can start to peel apart. In 2023, about 90% of old or faulty solar panels in the U.S. ended up in landfills.
