"The Environmental Protection Agency (EPA) has improved its car emissions testing following the Volkswagen diesel emissions scandal, but it could still take more steps, the agency’s internal watchdog said Tuesday.

The EPA did not actually discover the software that let diesel-fueled Volkswagen cars emit far more pollutants on the road than during regulatory tests, which sparked a international scandal that ended up costing the company billions.

The discovery came from outside groups like West Virginia University and the International Council on Clean Transportation. The EPA, meanwhile, was using legacy testing systems that were fooled by Volkswagen’s software."
