Tesla has asked state government permission to test-drive a caravan of electric, autonomously driven semi-trucks in Nevada, per Reuters' Marc Vartabedian.

CEO Elon Musk had already said he would unveil an electric semi-truck in September, and the new details help to fill in his possible thinking about the economics for a vehicle that would require a colossal battery: Researchers consulted by Axios in April estimated that the battery for a semi-truck would weigh three tons and cost about $70,000.

That could be prohibitive when you add in the pricetag for the semi-truck itself (the estimated cost for first-generation self-driving cars is about $300,000, so a truck would be much more), but a truck fleet company would be able to more easily absorb the expense if drivers were not necessary.

What it means: Since autonomous technology is not yet ready, and may not be until the 2030s, Tesla's idea may be to have a human-driven truck as the lead vehicle, and a caravan of semis behind, each programmed simply to follow the one in front of it, with no humans inside.

Fed signals it could yank economic support quicker as inflation sticks around

The Federal Reserve will consider pulling back economic support sooner "as the threat of persistently high inflation has grown," chair Jerome Powell said during a congressional hearing on Tuesday.

Why it matters: This is the biggest signal yet the Fed is backing away from its stance that soaring prices would be fleeting — a change that could shift its policies that underpin the economy.

Crypto meets the real world

The two largest countries in the world seem intent on effectively banning their citizens from participating in crypto, which poses a serious threat to the crypto agenda.

Why it matters: The crypto world is global — but the real world is fragmented into nation-states, each of which claims control of what happens within its borders.

Former White House Chief of Staff Mark Meadows is cooperating with the House select committee in charge of investigating the Jan. 6 Capitol insurrection, the panel said Tuesday.

Driving the news: Meadows, who failed to appear before the panel earlier this month, is believed to have insight into former President Trump's role in efforts to stop the certification of President Biden's election win.
