CHICAGO — When Elon Musk agreed this summer to build a futuristic tunnel to Chicago’s busiest airport on his own dime, many Chicagoans voiced doubt. And experts questioned whether Musk’s company could dig a 17-mile tunnel in a few years. A few days later, Mr. Musk, the chief executive of the electric-car maker Tesla, came under scrutiny for apparently smoking marijuana during an interview. The episode followed a summer of turmoil that led to the resignation of the company’s chief accounting officer and raised questions over Mr. Musk’s emotional state. Even if Mr. Musk’s engineers can dig a tunnel faster than other companies, his pod system, which the entire project is based on, is still a work in progress.
