They don’t. Realistically everyone knows where they are especially because map apps tell you, so they do whatever speed they want, slam on their brakes right before the cameras, crawl past them at ridiculously low speeds, get out of range, and then just go right back to doing whatever speed they want.
Sure it often slows things down a bit right in the corridor where the cameras are but if it was ever actually about safety, we would be using physics to slow cars down rather than cameras. Even in those corridors usually people are more focused on the camera than the road at that point so if anything its a distraction that makes people drive unsafely.
Red light cameras may be a different story but I doubt it

That’s why average speed cameras are now the preferred traffic calming measures on long roads. You can’t avoid ¯v = ∆s / ∆t, you have to stay under a certain speed while you’re between cameras.
