Back in the United States, the Justice Department has sued Fiat Chrysler, accusing it of using illegal software to bypass emissions regulations. The EPA accused Fiat Chrysler of installing the software on more than 100,000 Ram pickup trucks, allowing the car to bypass emissions control systems and spew significantly higher levels of pollution. Another car company, Volkswagen, has admitted to using software to rig some 11 million vehicles worldwide, allowing them to emit up to 40 times more pollution than standards allow.
