The Nissan self-driving car (or cars) set to debut in 2020 will still require a human driver behind the wheel, the company said in an update on the project.
Toyota is testing a suite of autonomous driving functions that it plans to offer on future products. It joins a growing list of carmakers doing the same.
Autonomous cars could be in showrooms by 2020, if Mercedes-Benz has its way. The carmaker's S500 Intelligent Drive prototype drove 60 miles on its own.
