SPECTRUM.IEEE.ORG | APR 2019 | 01 BACK STORY_ THE IEEE APP: Your mobile gateway to IEEE. EVEN A NON-MILLIONAIRE DESERVES A GREAT CAR nother day, another supercar. Lawrence Ulrich, our automotive contributor (that’s him, next to the US $525,000 Lambo) has driven more exotic automobiles than he can Download now recall. But he swears that he gets almost as big a kick from driving the latest electric cars or any other model that brings and get IEEE at new and exciting technology to the masses. your fingertips. “Any car that costs six figures is supposed to be amazing, and A there have been plenty of letdowns,” says Ulrich. “So one of the best things about my job is discovering a car that’s brilliantly designed and executed, but that regular people like me can afford.” He points to the Honda Insight Hybrid, in this year’s Top 10 Tech Cars, as a prime example of advanced technology and affordability. Ulrich lives in Brooklyn these days, but he hails from a three- generation family of Detroit autoworkers, including a grandfather and namesake who worked the metal presses—and had the missing fingers to show for it. Ulrich himself did time on a production line in the early ’80s, back when Detroit’s offerings were at a low ebb in terms of design, quality, and technology. The business has come back since then, in Detroit and around the world. The cars are better, and so is the manufacturing. These days, any global automaker—well, perhaps not Tesla—can routinely churn out 400,000 or even 500,000 cars a year from a single factory, using as few as 3,000 workers. “The same technology that has given us the most trouble-free, best-performing, most technically advanced cars in history continues to make human workers redundant, at least in terms of factory assembly,” Ulrich says. “It’s a sad irony, but there’s no going back.” ■ 04.19 CHARLIE MAGEE CHARLIE CONTRIBUTORS_ EDITOR IN CHIEF Susan Hassler, [email protected] ADVERTISING PRODUCTION MANAGER EXECUTIVE EDITOR Glenn Zorpette, [email protected] Felicia Spagnoli, [email protected] EDITORIAL DIRECTOR, DIGITAL SENIOR ADVERTISING PRODUCTION COORDINATOR Mark Anderson Harry Goldstein, [email protected] Nicole Evans Gyimah, [email protected] MANAGING EDITOR Elizabeth A.
