Elon Musk warned Tesla workers to prepare for a challenging production ramp-up as he previewed plans to build a mass-market vehicle.

The Tesla CEO said on the company’s Wednesday earnings call that building Tesla’s next-generation EV, set to enter production in 2025, will require Tesla workers to live and sleep on the manufacturing line at the company’s Texas factory.

Not the first time he’s done that to his employees.
