Apparently the "authorities" are idiots. They should talk to the local high school kids, as the instructions on how to hack these signs have been on the internet for a while now.

Gee, We didn't have things like that to play with when I was a kid. We had to risk our necks climbing water towers.

And these "experts" who cannot keep road signs from hackers are going to be in charge of our complete medical histories & credit reports.

Boy, I feel better now.
