Some people think it'd be reasonable to have every car reporting it's GPS position and speed to the government to stop people speeding, or to have facial recognition cameras on ever corner to catch criminals, or to make everyone carry an ID card that people can demand to see.

On the face of it living in a police state is safe, and secure, and actually increases your freedom to just live your life without pain. And if these systems were never abused that might be true. But sadly, the reality is that every time these things are implemented they end up being used against the citizens. So they're always a terrible idea.
