Cities vie to become hubs of self-driving technology

Are Detroit and the Silicon Valley the hotbeds for driverless car development? Not necessarily, says Brent Snavely of the Detroit Free Press. Last year, Goldman Sachs projected the market for advanced driver assistance systems and autonomous vehicles would grow from about $3 billion in 2015 to $96 billion in 2025 and $290 billion in 2035. In some cities, automakers, suppliers and technology companies are clustering to test their self-driving vehicles. In others, governors and mayors are beckoning the industry by changing laws or touting other inducements.
