Reminds me of this weekend -- State Patrol was pulling one car after another over after "viewing" their seat belt status from the side of the road when the cars were going 60-65 mph. Like they can make a reliable observation that way. The drivers got $124 tickets regardless of whether the belt was fastened when the trooper could actually see them.
That sucks.
The politicians won't dare make them all toll roads.
It is easier to just have the armed government highwaymen select victims arbitrarily.
That way, the peasants don't get all uppity all at once.
