Highway planners in Washington, DC, are talking about using infrared scanners to figure out how many people are in certain cars.
According to the Washington Post, the devices may be used when new High Occupancy Toll lanes – or HOT lanes – are added to the Beltway.
The private companies that will build and operate the HOT lanes are proposing the infrared scanners, which measure the reflectivity of human skin and can distinguish between a person and an animal or a dummy.
The scanners would eliminate the need for police or other observers to visually check each car to make sure it contained two or more people, the Post reported
Privacy advocates say the infrared images could end up being used against people in divorce courts.
