The so-called Federal Committee on Automation held its first meeting on Jan. 16, days before former President Barack Obama left office. Since then, though, the group led by Mary Barra, the CEO of General Motors, and Eric Garcetti, the mayor of Los Angeles, hasn’t met once, the sources said.

A spokesman for Lyft said the company’s president, John Zimmer, actually resigned his seat at the table “a while back.” That happened before a score of business leaders fled two White House-backed corporate advisory boards, citing Trump’s controversial comments about a neo-Nazi demonstration in Charlottesville, Va.

A spokeswoman for Google-owned Waymo, meanwhile, said they believe the Obama-era task force is not active under Trump.
