More than three years after Elon Musk stunned the auto industry with an electric pickup truck that looked more like a stealth fighter than a way to haul two-by-fours and drywall, Tesla said last month that it would begin building the vehicle by the end of 2023.

The announcement has helped fuel a recovery in Tesla’s share price, but also revived a debate about whether the often-delayed pickup, called the Cybertruck, is a work of genius or evidence of Mr. Musk’s hubris…

These challenges probably help explain why Tesla is two years behind schedule in manufacturing the Cybertruck, which the company plans to produce at its factory in Austin, Texas.

“Tesla thinks they can solve any problem and don’t have to learn from anyone else,” said Raj Rajkumar, a professor of engineering at Carnegie Mellon University, “and then they get stuck in a corner.”
