In a somewhat intriguing article arguing for private funding of new road and infrastructure projects, AEI's R. Richard Geddes makes this following aside:
More toll-funded roads wouldn't necessarily mean more toll plazas clogging our highways. Advanced satellite tracking technologies allow "open road" tolling, in which motorists would be charged per mile of road used--just as consumers are charged per kilowatt hour for electricity, per gallon of water, or per minute of cell phone use--without the backup at the toll booth. Private investors have the resources to utilize this new technology.
It might be a bit late in the game to make this complaint-slash-observation, but I'm not really sure that I'd want some governmental-business partnership tracking every place I drive with a satellite. We're increasingly trackable thanks to our cell phones and standard in-car technologies at this point, so the horse may be out of the barn, but the idea still gives me the creeps.
