Behind the scenes: In conversations on Air Force One and in the White House, Trump has acted out scenes of self-driving cars veering out of control and crashing into walls. He’s said he doesn’t think autonomous vehicles make sense, according to four sources who’ve heard him discuss the subject.

“You know when he’s telling a story, and he does the hand motions,” said a source who has heard Trump talk about hypothetical accidents involving self-driving cars. “He says, ‘Can you imagine, you’re sitting in the back seat and all of a sudden this car is zig-zagging around the corner and you can’t stop the f—ing thing?’”

“He’s definitely an automated car skeptic,” the source said. Another source said Trump told him self-driving cars “will never work.”
