I better put on some of that tinfoil, too. I decided a few years ago that the traffic cops are not traditional cops anymore, they’re just tax collectors.
They’re all over a party that’s too loud because they’ll probably be able to nab some underage drinkers at $400 a pop. But if you get your car broken into and need a police report for the insurance company, they’ll show up three hours later, treat you like crap, and complain to you that you’re wasting their time.
There’s no reason aside from revenue that freeway speeds decrease just because you cross a city line. If traffic it too heavy, the laws of physics will adjust the speeds down just fine on their own.
Also - I hate when a rural road drops from 55 to 25 instantly just because you entered the village limits of a podunk town nobody lives in anyway.
