RECIPE FOR RECALLS?

摘要

The 2010 Prius recall wasn't simply a braking problem; it was a software problem-and perhaps a harbinger of things to come. A decade ago, the average vehicle relied on a central internal computer to contro everything from headlights to wipers to automatic rear lift gates. But cars today have as many as 80 microprocessors; luxury models may have 100. Some of this technology is merely convenient, giving drivers more control over entertainment and climate systems, but most of it is crucially important because these chips and software improve safety, performance, and fuel efficiency.
