May 15 (UPI) -- The Environmental Protection Agency could do more to detect when automakers are attempting to cheat emissions testing, as Volkswagen did for years, the agency's inspector general said Tuesday.
The watchdog said the EPA's testing software at the time of the 2015 VW scandal was easily fooled. Federal regulators forced VW to recall thousands of vehicles that had so-called defeat devices installed on them. The software is capable of sensing when a vehicle is undergoing an emissions test and is able to fully optimize emissions control systems at that time.
