Tesla’s Cybertruck Powershare feature can now back up your home at the same time as a Powerwall 3, the company announced Thursday. Run together, the truck and the battery add more than three days of backup power, which Tesla says is the equivalent of nine extra Powerwalls.

It’s a feature Tesla first promised for 2025, and it’s showing up nearly two years after Cybertruck deliveries began. But it finally closes one of Powershare’s most annoying gaps.

A 2024 Tesla Model Y ran off Interstate 35 in rural Missouri, struck a guardrail, and killed its driver, a 64-year-old woman from Raymore. Troopers reported a single-vehicle wreck and said the car “went off the road.”

What they didn’t say, and likely didn’t know, is that Tesla’s own report to federal regulators says the car’s driver-assist system was engaged. This is part of an ongoing Electrek investigation matching reported crashes to Tesla’s redacted NHTSA data.

A US congressman is demanding the Department of Transportation explain what it’s doing about Tesla’s Autopilot and Full Self-Driving after an NBC News investigation surfaced dozens of videos of drivers apparently asleep at the wheel.

Rep. Raja Krishnamoorthi gave Transportation Secretary Sean Duffy until September 30 to answer five questions about the systems, which Tesla itself says “require active driver supervision and are not autonomous driving systems.”

The Boring Company has closed a $3 billion Series D funding round led by the United Arab Emirates, valuing Elon Musk’s tunneling venture at $23 billion.

That’s roughly four times its 2022 valuation of about $5.7 billion. And most of the case for it sits in tunnels the company hasn’t dug yet.

Senator Elissa Slotkin (D-MI) says she’s hearing rumors that President Trump is preparing to let Chinese cars be sold in the US as part of a broader deal with China.

She raised the claim Wednesday, tying it to Trump’s upcoming meeting with Chinese President Xi Jinping in Washington, which she said is coming “in just a few weeks.” There are many reasons to doubt these rumors.
