Look out Oregon drivers. Big Brother is coming for your cars.

The state launches its pilot program, called OReGO, July 1, marking the first pay-by-the-mile program in the U.S.

Oregon’s Department of Transportation has been trying to come up with a way  for years to replace the gas tax, which has seen declining revenues thanks to an influx of hybrid and electric cars and people's move away from driving, Fox News reported. 

This new program would charge driver per mile driven on Oregon roads, currently set at 1.5 cents per mile.

But while most of the focus has been on the complaints about the fairness of this system from drivers, there are also major concerns about privacy.

Miles are tracked using third-party GPS trackers, according to Torque News. These trackers go into participants' cars and have the capability to track and store your car's every move.

"To put a GPS monitor in everybody's car, the government already knows too much about us as it is," Jeff Kruse, a Republican state Senator told Fox News.

The program is currently voluntary and capped at 5,000 participants. But ODOT hopes to expand it and make it mandatory within the next few years.
