California has been pushing for this since the days of Schwarzenegger. The pols want a high gas tax AND a pay-per-mile fee.
What I’m noticing lately is HOV lanes being converted to toll lanes one freeway at a time. I drive the 110 almost every day and notice those toll lanes are nearly empty - yet the media has called them a “great success” - with plans for expansion. The California FedGov wants us to pay (and pay and pay and pay) for the roads twice, three times, and more.
In a few years, all HOV lanes will be toll lanes - and then the entire freeway system will become toll roads.
It’s coming.
