China will wait another two years to set their vehicle-to-vehicle communication standards that will be vital for driverless cars.

As reported by Autonews, their aim is to establish a national standard that will speed up the implementation of fully autonomous cars in the world’s biggest auto market.

Earlier this year, SAE-China put together a 450-page roadmap laying down specific policy objectives for basically every aspect of the automotive industry, including driverless vehicles and electric cars. Still, the document stopped short of establishing a unified standard for car-to-car communication as well as communication with the surrounding infrastructure.

China will lay the foundation for these standards in 2018 in the next update of the roadmap, though more exact guidelines will be developed and agreed to by all automotive brands between 2020 and 2025, according to SAE-China boss Fu Yuwu.

“You can’t fundamentally use different channels [of communication] right? So in the end we need a unification process,” said Fu. “This will be complicated and difficult but is in the best interests of the industry.”

With this in mind, it’s possible that China’s method of central unified planning will prove more efficient than in countries like Japan, whose top three automakers aren’t exactly in agreement on these standards.
