Tesla pressures are clouding Elon Musk's solar gambit. The $32 billion electric-car maker he founded and runs has missed its delivery target again. That's bad news for a company aiming to quintuple production in short order. A fatal crash also has invited scrutiny of Tesla's autopilot feature. These concerns further undermine an already questionable effort to buy SolarCity.
Some 14,370 customers received keys to their new Tesla in the three months to June, 15 percent below Musk's stated goal. There is a silver lining: about 5,000 Model S and X vehicles also were on their way to new owners.
