You know, like Volkswagen has/does in US-Amerika? The company inserted a device into almost 500,000 cars meant to trick emissions testing, the EPA says. Volkswagen is not denying this.

There are almost 500,000 vehicles on American roads with the devices installed, according to the EPA. Volkswagen must now pay to repair the emissions systems in affected cars. The government may also fine the company as much as $18 billion.
