One day in December, a self-driving bus in Gunma completed an 18-km run from Maebashi to Shibukawa and back, dropping fare-paying passengers off at designated stops and navigating public roads.
The driver, who got the bus humming with the push of a button, stayed behind the wheel but was hands-off most of the time, keeping intervention to a minimum. The bus, sporting an array of sensors and cameras, was limited to a maximum speed of around 30 kph.
The bus completed the circuit from Gunma University to Shibukawa Station in about an hour, twice a day for nine days, as part of a pilot program set up by the school, a local bus line, the Gunma Prefectural Government and NEC.
