The coming US-China race over 5G in cars

It has been more than two years since people started being able to talk to each other over 5G networks. Now cars can use 5G technology to talk to each other, too.

But the business could develop into another source of U.S.-China competition. Chinese companies have been working longer on such vehicle communications based on advanced cellular technology, using a standard the U.S. embraced only last year, and they hope to take the lead in global markets. The U.S. and its allies, meanwhile, are cautious about using Chinese communications equipment.
