Hence, by setting a lower speed in a particular area just to appease residents, your piece of paper, or a local politician, you're gradually eroding the safety in other areas. Of course most residents when told this will fly off the handle as they were never asking for a lower speed based on a logical argument, but rather solely an appeal to emotion (won't SOMEONE think of the CHILDREN?). But anyway, the key is, if you actually want people to go slower, setting lower limits can be counter-intuitive.
Certainly counter productive. I'm interested in the legal mechanism whereby speed limits are set. I know there's at the very least a guide to set the limit at 85% of the mean unrestricted speed for any given bit of road. In fact one report had that as not so much a guide as a requirement.
Which begs a bunch of questions. Not least of which is "how do you establish the mean unregulated speed?"
Only, I've never encountered a stretch of road with a sign saying: "Hit it guys, we're timing you to see what speed you're comfy with".
