It’s behind a paywall, but the WSJ columnist looks into a question touched on repeatedly in this space and connects it to the unpredictability with which juries may credit expert testimony, as an Oklahoma jury recently did in Toyota litigation:
Toyota had been vigorously fighting hundreds of complaints that its cars are prone to unintended acceleration. Now it’s moving toward a global settlement as a consequence of a single Oklahoma lawsuit that appears to establish that Toyota can’t prevail if it can’t prove a negative—that its software didn’t go haywire in some untraceable and unreplicable manner. …
The Bookout jury was apparently impressed by the testimony of software expert Michael Barr. He said a single “bit flip” (the smallest instance of data corruption) could cause uncontrolled acceleration when the driver had been using cruise control, stopped using cruise control, then resumed using cruise control to let the car accelerate back to its selected speed. …
The connection to Ms. Bookout’s crash, which didn’t involve cruise control and took place on an exit ramp? None, except Mr. Barr claimed that “software failure is consistent with the description of the [Bookout] accident” and “more likely than not” a factor.
Jenkins notes, as have others, that if some mysterious and unreplicable bug is causing Toyotas to accelerate suddenly while disabling the brakes, it seems to differentially appear in cars being driven by elderly drivers, which are greatly overrepresented in the crash statistics.
