What happened
On 11 November 2020 Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) granted type designation to Honda's Legend. The car carries Traffic Jam Pilot, which makes it a Level 3 automated vehicle. MLIT acted after the National Traffic Safety and Environment Laboratory examined the car's conformity with the safety standards. It called this the world's first type designation of a vehicle with an automated operation device. In expressway traffic jams, the device monitors the surrounding traffic and drives the car, following the vehicle ahead within its lane. MLIT states that the device aims to lighten the driver's workload in traffic jams. It works only within the operating conditions that the minister set. Honda's outline adds that it engages below about 30 km/h and runs at up to about 50 km/h. When the conditions are no longer met or a fault occurs, it warns the driver to take over. MLIT says that drivers must not overtrust it and must stay ready to drive. The release gives no outcomes from driving on public roads.
