When it comes to dashboard displays that are more like smart phones, two things are clear: Customers want them, and automakers are intent on supplying them.
But are they really a good idea?
Car companies answer with an emphatic yes. They say outsized dashboard displays that behave more like smart phones will boost revenue and attract buyers. And they also insist the new screens will make driving less dangerous, because of well-integrated voice controls and large touch screens that will keep drivers from fumbling with more dangerous mobile phones.
But the increasingly elaborate screens have also sparked a broad debate about how much technology is appropriate in a car.
"I think they (the screens) raise serious public safety questions," said Joe Simitian, the former California lawmaker who spearheaded the state's laws on phone use while driving. "From a legislative standpoint, this is going to be something legislators struggle with for years to come."
But for automakers and their customers, the souped-up screens are proving irresistible.
In an Audi A3, for example, drivers who sync their phones with their cars can check for mentions of themselves on Twitter and see those tweets on their dashboards—although not their full Twitter streams. They can upload photos taken on smart phones and request mapping to the place the photo was taken. Text messages pop up on the dashboard, in addition to being read out loud.
Up to now, dashboard technology hasn’t factored highly into most car buying decisions, but carmakers expect it to become increasingly important over the next 3-5 years. A recent study by the market research company J.D. Power found that about 15 percent of consumers rule out buying a car if it lacks the latest technology, compared with just 4 percent a year ago.
