A proposed U.S. crackdown on sharing technology with China could threaten the development of self-driving vehicles, the Wall Street Journal reports.

Why it matters: Many companies developing autonomous driving systems split their work between the U.S. and China, with offices, investors, engineers and customers in both countries. Unscrambling that egg could be difficult.

  • “Our company would be split in half,” David Liu, CEO of Plus.ai, told WSJ. The American self-driving software developer recently teamed up with Chinese truck maker FAW Group.
  • The U.S.’ proposed controls are “a cloud hanging over every technology company,” he said.

The big picture: China's aspiration to dominate the AV field is heavily dependent on R&D centers in Silicon Valley.

  • Even though some companies don't plan to deploy AVs in the U.S., there's a certain cachet that comes from validating their technology and securing investment in California — the epicenter of AV research.
  • 14 Chinese companies have licenses to test self-driving cars in California, WSJ reports.

What to watch: The Trump administration could use technology controls as a bargaining chip in its ongoing trade confrontation with Beijing, China expert Michael Dunne, CEO of ZoZo Go, tells the paper.

  • “We’re at a crossroads,” Dunne says. “Will it be reciprocal openness or reciprocal protection?”

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

U.S. vs. Google — the siege begins

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
