In Minnesota red light cameras and such automated ticketing systems were determined to be illegal (for the state):

The result? Minnesota isn't experiencing some sort of Mad Max like traffic apocalypses, things seem pretty normal and I don't know of any dramatic disparity between places that use such cameras and those who do not. Meanwhile corruption and other issues cloud the traffic camera world... it's a product that arguably encourages / benefits bad actors, and possibly nobody else despite what we might otherwise think it does.
Sometimes despite what we might want, we just don't need smart stuff and using it just allows for bad actors and little else. There's lots of talk about home smart speakers but then on HN we see all sorts of discussions of people who bought them and admit, they really don't get a great deal of utility from them... so perhaps we've just paid for a product that actually provides google or amazon more utility than we ever get...
As Frank Herbert said:
“Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.”
In Dune the result was that mankind eventually did away with "thinking machines" as it was clear the risk was greater than the reward.
