No, they don't. Did you miss this line?
The people coming thru that are not locals don't know that the sign is there until its difficult or simply too late to slow for it. Plus, they are targeted unequally by these kinds of towns that exist from traffic ticket money - the cops go after the out-of-state license plated cars. Plus, they don't know that, in this one particular area, unlike most anywhere else in the nation, 35 means 35, when most places 35 means maybe 40. If you do the 35 in places where 35 means 40, you get people tailgating you or pbutting you, possibly briskly, neither of which is an optimal safety situation. And, of course, they enforce this limit 1 inch after the sign which is placed as far outside of the obvious reason for it as they can, making it unusual in this respect.
I'm extremely alert when I drive, but my friend driving behind me didn't see the sign as soon as I did, and was still traveling highway speeds when he pbutted it. I got slowed down, fortunately. He got a $200 ticket that he couldn't really afford.
We exited Florida by taking Interstate 75 up to Interstate 10 and over to Jacksonville area to catch Interstate 95 back to Virginia and Maryland, thus avoiding Rt 301. That's farther, but far safer to the wallet. With a racket like this going on in these small towns, the public doesn't need robbers to hold them up and take their money, they have the local cops filling in for them quite nicely. Its not "enforcing the law", its stealing, plain and simple.
