Subaru Corp. aims to start selling vehicles equipped with the equivalent of "level-2" autonomous technology, which can steer, accelerate and slow down on ordinary roads, in the second half of the 2020s, company officials said Tuesday.

Several automakers, including Toyota Motor Corp. and Nissan Motor Co., already offer level-2 autonomous vehicles for use on expressways. But developing such vehicles to run on ordinary roads has been a challenge, due to the need to respond to unexpected scenarios such as pedestrians' movements in order to avoid accidents.

Subaru plans to develop a next-generation system using its EyeSight Driver Assist Technology and artificial intelligence to recognize a traffic lane even when the white line on the roads cannot be seen.
