I agree. I was able to talk to my local SF supervisor the other day and congratulate him on his work with speed cameras and red-light cameras. He shares the same position as you: there is no constitutional right to drive one's car on public streets without enforcement of the rules.

We recently got permission to expand red-light cameras and I'm hoping that this kind of neutral machine-based enforcement of laws helps move us to a more law-abiding society. Civil liberties require civilization. Abdicating public space to the anti-social only allows for a de-facto rule by the uncivilized.

It's not "neutral machine-based enforcement", it's a general purpose panopticon that tracks and logs everything, ready to be queried later by arbitrary people for arbitrary reasons.
