Visual performance? = bigger $ ideology
For the speedometer.
All tho in thought that visual perk would all ready be known to cost more in general practice proven explicitly since the muscle car era really got that ball rolling, even if the vehicle is not performance.
.....
As for the cost for speeding here in this small minded town is "If you can catch them" territory the price varies on the type and general cost of the vehicle.
And as for road signs, any department cost soon to realize that the all ready complicated to most signs are needing to be made more complicated to only exaggerate the need for as to sustain the money roll.
Just thoughts on the sign departments that plan and study the methods currently in traffic use and that seem to work often to only go and place a hey I did that, look at me! sign that meddles in that well sounding orchestra that showed some promise.
...ever notice the signs in the large progress (shopping squares) areas do rarely change those signs?
