Sure but the argument is what can be controlled. The major portion of drivers are going to be driving as fast as the road allows, some portion faster and some will drive as fast they read on the sign (as they tap on their phones). We can ticket the reckless drivers, maybe have devices to reduce the average but raising the speed limit to the speed of the bulk of traffic makes sense, as per argument in article.
