Odds are still in your favor to speed. What was the traffic volume over the course of that week to calculate the odds? I see more and more in residential areas at 25mph where they install digital signs indicating current speed through highly traveled streets to hopefully slow down drivers but idea if that theory works. I'm assuming it doesn't hurt given how drivers are easily distracted but I'm curious if these sign log any data.
