They're twinning the highway near where I live. For the past few days, every time I go past one particular section when this one particular monster CAT machine is working, I get a k-band alert. No LEOs in sight anywhere. And if that machine is parked, not moving, I don't get an alert. I'm wondering if it maybe has some sort of k-band sensor like the automatic doors use to detect people or other objects in its path?
And if that's the case, one of those machines had a broken sensor yesterday -- all kinds of cops and a crowd of construction workers standing around staring at a big machine that had backed right over the top of one of the workers parked cars! Not funny, I know, but I couldn't help laughing!
