This is a dangerous attitude.

We don't need mass surveillance for traffic control. It can be done by the police if they really wanted to do it. Truth is, they don't care enough about road safety. This is about surveillance of citizens for control. First step is just infrastructure setup - next step is using it to prosecute those who dare to challenge the rise of fascism.

Be an advocate for your own rights to privacy. Don't simply accept it as normalcy.

Unless you want a police officer on every street corner at all times, no, it cannot be "done by the police".
