This week's Question: With backup cameras now mandatory in today's vehicles, screens in cars are increasingly becoming a standard feature. At the Consumer Electronics Show in Las Vegas this month, Corning Glass presented a demo of a new kind of automotive interior — one making full use of touch-based smart glass, from the windshield to the console.
