Nissan CEO Carlos Ghosn says that the company will get self-driving cars ready by 2020.

But, according to the Associated Press, there would be less of a chance to drive them because of government regulations, which is the biggest challenge for autonomous vehicles.

Ghosn had previously promised that the self-driving technology would be in development, and he has reaffirmed the public today about said promise.

"The bigger hurdle for such vehicles becoming readily available to consumers is approval from regulators around the world, he told reporters at Yokohama headquarters," Ghosn said.

IB Times reported that the company aims to introduce types of vehicles that can find the way without human intervention in "nearly all situations, including complex city driving."

Aside from the autonomous driving technology, the cars would have improved connectivity and low emissions. Nissan is banking on electric cars, rather than other zero-emissions technologies.

A number of heavyweight companies are exploring with this technology; Google has released its first prototype autonomous vehicle that will be tested on the road this summer.

But Nissan is not seeking the same goal as Google because it will be focusing on driver assistance and enhancement, rather than taking away control from the driver.

Ghosn further said Nissan may come close with a driverless car, but it is not necessarily the goal of the company.

According to Huffington Post, the executive was quoted saying, "Our cars will be ready.That is the car of the future.... But the consumer is more conservative. That makes us cautious."
