Is it a stretch to think, that with modern technology (transponders, license plate readers, etc.), that all roads will be toll roads eventually?
Think about it. Cameras and transponder readers could be installed everywhere. Even if you are just driving on local streets to go do your grocery shopping, they would bill you for driving three miles down the road.
In that case, I predict these "local street tolls" will meet the same fate as the downtown parking meters in many towns. They were taken away because local merchants saw them as a disincentive for customers to do business there.
