People seldom hit construction workers in PA because they're never actually working...
Seriously, we do have a lot of jobs where the work is done at night so in theory it doesn't impede rush hour. In practice, however, it still screws up everything because the work area is still posted at a lower speed even though no workers are in it. Often there isn't even a hazard like a closed shoulder to be concerned of. This kind of frustration is what makes people tend to ignore the lower limits, so when there really are workers, they might assume the boy is still just crying wolf.
The trick is finding dimmable ones. Even then, you have to use LED dimmers or you'll just end up having a dimming range that is either off, or about 50-100%-- if it works at all. Still better than CFL.
I found $1 dimmable 40-watt equivalent LEDs at Goodwill a few months ago. They were probably power-company-subsidized, but that's still amazing. I bought four, and wish I'd bought more.
May I respectfully disagree with your off-topic rant and incorrect recall of history?

Also, stop using sneaky ad hominems like "blind".
