Shoddy infrastructure has become a roadblock to the development of self-driving cars, vexing engineers and adding time and cost.
Poor markings and uneven signage on the 3 million miles of paved roads in the United States are forcing automakers to develop more sophisticated sensors and maps to compensate, industry executives say.
Tesla CEO Elon Musk recently called the mundane issue of faded lane markings “crazy,” complaining they confused his semi-autonomous cars.
An estimated 65 percent of U.S. roads are in poor condition, according to the U.S. Department of Transportation, with the transportation infrastructure system rated 12th in the World Economic Forum’s 2014-2015 global competitiveness report.
