The throwback drive-in, conceived years ago when the world's richest man was still a Los Angeles hometown hero, bows in a radically different era.

Tesla CEO Elon Musk has launched the company's first Diner & Drive-In in Hollywood, Los Angeles, combining retro Americana with robot servers and synchronized movie screenings. The diner debuted on Santa Monica Boulevard, with hundreds of guests forming lines on opening day.

For months, protesters have gathered outside Tesla showrooms in response to Elon Musk’s role in reducing US government spending as part of the Department of Government Efficiency.
