BEIJING/PALO ALTO, U.S. -- Chinese developers of self-driving cars have nearly doubled their presence in California road testing, where the pursuit has turned into a two-way race between the world's leading economies.
China claimed eight of the top 25 companies by kilometers driven last year, up from five in 2017, according to data compiled by Nikkei from reports submitted to California. The U.S. held the lead with 13.
