How do the cars know what the speed limit is? Is the state providing this data in a standard format that cars are expected to download? Are they using transponders on road signs to send signals to cars to tell them what the limit is?
I’ve lost track the number of times I’ve exited a construction and not known what the hell the speed limit is because previously it changed somewhere within the zone before the construction started.
Or worse, a total lack of signs on rural roads.
Just had a case today in WI where I left one road at 55 MPH onto a county road, and had no idea that the new limit was 45 until we checked Google Maps.
