But there is really no need for red-light cameras at all. If there is an intersection with lots of red-light runners, it means the yellow isn’t long enough. Add a second or two, and the red-light runners disappear.

That's really a silly argument. That's like saying that the best way to eliminate red-light runners is to remove traffic lights entirely.

Yellow intervals for traffic signals aren't just pulled out of thin air. The yellow interval is computed based on engineering principles, with the travel speed of the roadway as the main factor in determining the minimum yellow time for safe stopping.

It works every time it's tried.

Evidently your goal isn't safety, but control over people you don't like.

“Yellow intervals for traffic signals aren’t just pulled out of thin air. The yellow interval is computed based on engineering principles, with the travel speed of the roadway as the main factor in determining the minimum yellow time for safe stopping”

In my city, I think we have “smart” signals that go yellow when my car is about to go through the intersection. I suspect it is OK to go through, but need to make a very quick decision.

It is not too hard to imagine the light being set to change so that it is not OK to go through.

There is one intersection right by one police station that takes a while to cycle all three directions. One day, the light went green and bam, it went yellow. I thought it was a malfunction. The next day, bam it goes yellow, one car goes through the red. Bam, a squad car materializes. Maybe it wasn’t a malfunction.
