For most people, a half-second delay is something to shrug off. For Steve Reed and Trent Lester, a blip that small might raise a red flag in their safety-focused industry. They work at the Subaru factory in Lafayette, Indiana, the company’s only facility outside of Japan and one of the world’s most advanced automobile plants, where each year more than 6,000 people produce up to 400,000 Legacy, Outback, Impreza, and Ascent models. Reed and Lester collect thousands of data points every second, from the status of air compressors to the amount of antifreeze that’s dispensed into each vehicle.
