>>The cameras cannot make people drive stupid.<<
Actually, that is false. The cameras most definitely do that for many people - they know it’s a camera intersection, the light turns yellow, they slam on their brakes even though they actually had plenty of time to go through. It actually happens a lot.
And the more people slam on their brakes, the more rear-enders there will be.
You are blaming an object for your foot pressing the brake pedal. Humans decide how to act, not cameras.
