Tesla is hardly the only player in the nascent electric truck market — as Bloomberg notes — as big companies like Daimler and Cummins are moving toward commercialization.

Why electric trucks matter: Trucks, especially big rigs, are a small percentage of vehicles on the road but use lots of oil. (Check out the chart below, reconstructed from the International Energy Agency's new World Energy Outlook 2017.)

In what amounts to IEA's base case (a model of existing and officially announced policies), oil demand for trucking swells to 20 million barrels per day in 2040, led by that sharp increase you see in diesel demand for heavy-duty freight.

  • It's one reason, though hardly the only one, why IEA does not forecast a peak in global crude oil demand through the end of their analysis period in 2040.

The bottom line: Widespread deployment of electric heavy-duty trucking — alongside other alternative fuels and stronger fuel efficiency mandates for diesel-powered rigs — could alter the trajectory of oil demand in coming decade if Musk and other players can make it cost-effective.

CDC updates guidance to say coronavirus can be spread through the air

The CDC updated its guidance on Friday to acknowledge that the coronavirus can be transmitted through the air at distances farther than six feet and through "droplets or small particles, such as those in aerosols" like coughs or sneezes.

Why it matters: The update — which was little noticed until a CNN story was published Sunday — comes months after scientists pushed for the agency to acknowledge the disease was transmissible through the air. The CDC previously said that close person-to-person contact was the bigger concern.

Top Mueller prosecutor: "We could have done more"

Andrew Weissmann, one of former special counsel Robert Mueller's top prosecutors, says in his new book, "Where Law Ends: Inside the Mueller Investigation," that the probe "could have done more" to take on President Trump, per The Atlantic.

Why it matters ... Weissmann argues that the investigation's report didn't go far enough in making a determination regarding Trump's potential obstruction of justice: "When there is insufficient proof of a crime, in volume one, we say it. But when there is sufficient proof, with obstruction, we don’t say it. Who is going to be fooled by that? It’s so obvious."

Trump's next moves in Supreme Court fight

President Trump's choices to succeed Justice Ruth Bader Ginsburg are down to two women, both federal appeals court judges.

The frontrunners are Amy Coney Barrett of Chicago, the early favorite, and Barbara Lagoa, who is viewed as easier to confirm. The Senate confirmed Lagoa 80-15 last year, so many Democrats have already voted for her.
