I have heard about a similar concern in other parts of the County.I'm not sure if they do enough, or if it is when they do it. It's almost like there's an unwritten rule not to do traffic enforcement during peak traffic periods unless absolutely necessary. Two examples from my little neck of the woods.
1. The long straight section of 249 between Tall Timbers and Piney Point. The speed limit is 50. I've encountered people traveling close 70 to HLSS in the morning, especially the closer you get to 8:00am.
2. LE will not run radar in the 30 MPH section of downtown Piney Point during morning and evening rush when people are flying, but they will during lunchtime when traffic is much lighter.
