The state says it's about fairness and modernization, but the deeper I look, the more it resembles a permanent surveillance and revenue network disguised as transportation reform. What's being tested today through Caltrans and the State Transportation Agency is the blueprint for total mileage monitoring tied to personal identity.

California is advancing a plan to replace the state gas tax with a mileage-based road charge that taxes drivers by distance traveled. The effort is led by the California State Transportation Agency and Caltrans under a multi-year Road Charge program first authorized by SB 1077 in 2014 and extended and refined by SB 339 in 2021. The state's stated purpose is to stabilize road funding as fuel-tax revenue declines.

As of October 2025, the program is still in the pilot and data-gathering phase. No statewide mandate or rate schedule has been enacted, but Caltrans has already built the structure necessary for full implementation. What is being called a "test" now is the foundation for what will later become mandatory reporting.
