Personally, I think it's a good idea.
I've asked the local police dept. to place one of those small trailer-signs showing "Your Speed" in front of the house, but there is a
waiting list!
I'm sick and tired of seeing too many a-hole's, in their huge SUV's, talking on the cell phone, accelerating like their at a drag strip only to slam on the brakes to negotiate the tight turns which are on the road I live on.
Living "out in the sticks", many of the roads are two lane, narrow, winding roads, with many elevation changes, blind spots, etc., and these morons who are in such a hurry, talking on their cell phones, and even applying make-up, (all of which I witness almost every day) is ridiculous.
I'm certain there are a good many who feel the way I do. If you don't want to be harrassed by "Helen", or "the neighbors", show some restraint. I personally make sure I'm doing the speed limit whenever I'm in the area where I live.
Maybe it's just getting older, but there are lots of places to "open 'em up", but, neighborhoods are not the place. I often take the SS out to the local interstate, bypass, etc., and "stretch his legs".
I don't want idiots racing past my house, and I doubt anyone here does either. I say "Nail the idiots any chance you get."
