If that is the argument, then we should just drop enforcement of traffic rules alltogether. Because people don't want to have an accident?

But driving reckless and having a big well protected car helps of course, so everyone speeding would want even bigger and better armored cars.

Those daring to drive light vecicles or even bicycles, screw them?

Here in germany we managed to have automated red light tickets, without saving video at all btw. Just a picture (or multiple) of the incident. The picture is tied to the traffuc lights logic so knows when red light was on.

Now I am not really a fan of them, but they do work without mass surveillance.
