This is some thing we all know about and truthfully it does not start with the police but instead in general with a city council, mayor, county administrator.
I am interested in people's perceptions.

No LEO bashing though. (that really is not what this is about)
In the 1970's, with the US Gas shortage the US government set a mandate of 55 MPH for a maximum speed limit. This limit was set for fuel economy.
By 1979 and through the 1980's there was a campaign of "Drive 55 and bring them back alive". They found that with the older cars that by slowing down more lives were saved with accidents.
That Mandate is no longer in effect. There are many states that allow 65 MPH and 70 MPH and even 75 MPH in some Plaines or Western States. Review the death rate and it is better today even with the increased speed. The Vehicle Manufacturers have done a good job for safety. The US Federal Safety laws have pushed for this as well.
The reason for speed limits is that under conditions speed can cause an accident as the person will not be able to react in time.
Everyone in Michigan knows that if you are from out of state and drive in Ohio, even by 0.1 mph you will be stopped and fined.
In many locations in the state of Michigan, 5 over is acceptable by the local police. In some areas on major Interstate Highways up to 8 or 9 mph over is ignored.
If certain municipalities decide to take advantage of how people drive then whose fault is it? It is the driver's fault. Yes or no were you over the speed limit?
So, I have no problem with police departments enforcing the law.
I do have issues with the automated systems, as I do not understand how one is allowed to fight it.
I do have issues such as in Georgia that have had Construction areas up in place for 5 years with no construction under going. I have a problem with this as if it is posted 55 and you do 55.1 the fine is doubled. This is unethical as it is true that people were breaking the law, but to leave up a construction zone for 5 years to get more money is something I find to be in poor taste.
