A better solution would be to do regular speed studies and actually update the speed limits posted. Also, prevent municipalities from passing laws on their own speed limits and creating speed trap situations.

I see a lot of speed limits that are woefully out of date and/or very different from the 85th percentile speed on any one motorway.

Then we should just ditch the whole speed limit concept. You should be punished for variance from 85th percentile speed on a motorway in either direction. Too slow or too fast are both dangerous
