The Federal Trade Commission’s Office of Technology has issued a warning to automakers that sell connected cars. Companies that offer such products “do not have the free license to monetize people’s information beyond purposes needed to provide their requested product or service,” it wrote in a blog post on Tuesday. Just because executives and investors want recurring revenue streams, that does not “outweigh the need for meaningful privacy safeguards,” the FTC wrote.
