“Speed limits are advisory.”
I live in Florida. The various agencies are self-funded. That means they’re out there writing code enforcement violations (fines.) The local government has over $500k budgeted as income that is from code violations. So, you might ask, what if nobody violates the law? They’ve lowered the speed limits on short sections of roads where it is easy to set up traps. (I have lost all respect for “law” enforcement. They are just one short step from uniformed robbers.)
An unincorporated village near me lowered speed limits from 50 to 25 on a stretch of road that had been 55 forever.
Now their patrol force is driving new Tahoes instead of 12 yr old Ford Crown Vics.
I suspect the boys in blue benefitted from the “incentive” program.
