This week, car company Volkswagen came under fire for installing software in its cars that would automatically detect whether one of their vehicles was undergoing an emissions test.
“The company installed a so-called ‘defeat device,’ which is not a device like we think of devices,” says Ben Johnson, Marketplace Tech host. “It’s actually a piece of software or firmware.
