There's no reason a guy with a rifle in the trunk and a bullet proof vest needs to spend most of their day dealing with minor traffic code things on the highway.
I would much rather armed cops be much better trained, and much fewer in number, and only activated on the rare occasion that there is a need for them. Traffic cops should be better trained on things like headlight aiming, illegal lift kits and tire modifications, exhaust rules etc...
Most places already have plenty of laws around these things (many of them federal) but cops will never go after someone for having a dangerously lifted truck with illegal exhaust for some reason, even though they are happy to cite someone for a burnt out license plate bulb.
I fear adding yet more rules they don't enforce just adds tools to a questionable toolbag.
I'd love for things like this to be enforced, though. Often feels like the roadways are a warzone heh.
