This is a little trickier because if you just park your car in the middle of an intersection, it's obvious who is the problem (it's you, or at least the car even if it can't be traced back to you). If the problem can be anybody with a few dollars' worth of electronics within 100ft of an intersection, then it isn't so obvious. Now we need FCC party vans, or at least the cops need another doohickey now.

Right. And you think people will plant electronic doohickeys at junctions in order to make them 60% less efficient? The kind of ne’erdowells who get their kicks by getting away with recklessly causing mild inconveniences to other people? What else might they do if left unchecked? Hog all the WiFi bandwidth at the library? Put some plastic into the cardboard recycling bin?

  > Right. And you think people will plant electronic doohickeys at junctions in order to make them 60% less efficient? I think they'll compromise the gas station chain's IOT devices. Similar to when the POS devices for Target were attacked in 2013. They didn't have to have someone taking the in-person risk of going up to each device in person; they hacked a small HVAC company in PA that had "remote access to Target’s network for electronic billing, contract submission, and project management purposes". https://www.commerce.senate.gov/services/files/24d3c229-4f2f-405d-b8db-a3a67f183883 https://www.commerce.senate.gov/services/files/24d3c229-4f2f...

    Join the dots between that kind of acquisitive, financially motivated crime, and the posited threat model for smart traffic lights. I don’t understand how someone can make money by disrupting the light cycle to make it a bit less optimal.

      It's not always about money. Sometimes there's a larger goal of just being disruptive. Imagine gridlock traffic on an election day. Imagine that traffic being mainly focused on voting districts that are likely to vote for a specific candidate.
