Connected cars are a “huge emphasis,” Joe Lawrence, chief operating officer of Porsche Cars North America, said Wednesday at the Bloomberg Innovation Forum in Atlanta. “Recognizing the phone is so ubiquitous in every sector, how do we integrate that into driving experience in a way that is safe and enjoyable?” Automakers can benefit by working with technology developers such as Google Inc. and Apple Inc., and “I think all manufacturers are talking to” those two companies, he said. Connected-car technologies were the problems most often reported by owners in a J.P. Power vehicle reliability study released last month.
