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.

Hurricane Zeta has killed at least one person after a 55-year-old man was "electrocuted by a downed power line" in Louisiana as the storm caused widespread power outages Wednesday night, per AP.

What's happening: Zeta made landfall south of New Orleans as a Category 2 hurricane earlier Wednesday before weakening to Category 1. But it was still "battering southeastern Louisiana and southern Mississippi with life-threatening storm surge, high winds, and heavy rain" late Wednesday, per the National Hurricane Center.

NIAID director Anthony Fauci told the Journal of the American Medical Association on Wednesday he doesn't expect a COVID-19 vaccine to be ready until January 2021 or later.

What he's saying: Fauci said during the interview that the U.S. was in a "bad position" after failing to keep case numbers down post-summer. "We should have been way down in baseline and daily cases and we’re not," he said.
