China is creating roadblocks for U.S. auto makers and tech companies to bringing self-driving cars to the world’s largest auto market.
Citing national security concerns, China is limiting the amount of mapping that can be done by foreign companies, as General Motors Co. , Ford Motor Co., Alphabet Inc. and Apple Inc. rush to develop self-driving cars or the software behind them. High-definition maps are crucial for autonomous cars to help them discern their exact location, navigate tricky intersections and avoid fixed objects such as buildings.
Global car makers already need to form a partnership with a local company to open factories in China, but some are skeptical they will be able to find a way to operate their autonomous-car software in China because of the mapping restrictions.
