Global car makers are feeding real-time location information and dozens of other data points from electric vehicles to Chinese government monitoring centres, as President Xi Jinping steps up the use of technology to track Chinese citizens. The data-gathering generally happens without car owners' knowledge, the Associated Press found. More than 200 car makers selling electric vehicles in China -- including Tesla, Volkswagen, BMW, Daimler, Ford, General Motors, Nissan and Mitsubishi -- send at least 61 data points to government-backed monitoring platforms, under rules published in 2016. The firms say they are complying with local laws, which apply only to alternative energy vehicles. Chinese officials say the data is used for analytics to improve public safety, facilitate industrial development and infrastructure planning, and to prevent fraud in subsidy programmes.
