Here in California, our electronic pass came with an aluminum wrapping, a grandson, the family IT suggested that we keep in the original package, except, when we go through an electronic toll both.
Most drivers mount them on their windshields, which means their signals are captured by any sensor on the roads that tracks those signals.
There was a recent study on what vehicles are causing traffic jams on a road that goes between two counties.
The newspaper article told about how cell phones and their Fast Past told the sensors where the car came from and when.
No one besides my wife, myself and our IT grandson were concerned about this massive data capture.
Definitely good advice!
I’d still be paying cash for tolls if it wasn’t more expensive. (PA has a 25% markup for paying tolls in cash)
