More dangerous to drivers (especially those inclined to drive at dangerous speeds), maybe. More dangerous for pedestrians? I'm not sure about that -- especially if nobody's obeying the limit in the first place, getting drivers to slow down at all is a good thing. Or do you like to have drivers speeding at 50MPH down the narrow side street (signed at 20MPH) your kids cross every day to get to school?
