In a state I lived in, these kinds of camera-based enforcement of vehicle laws were ruled unconstitutional (state constitution). The argument was that traffic laws apply to the person driving the car, not the car, and it's too difficult to tell from videos who is driving the car. There were probably other arguments against them but basically the state supreme court decided there was no way a camera could establish evidence at the level of certainty needed.

It's odd now that I think of it because traffic cameras used for other reasons have been used in felony investigations (eg, murder). My guess is in those cases they have to establish that the person being charged was likely in the car?

I think it's the automatic charging aspect of it.

In Croatia, the owner of the vehicle is responsible to identify the person driving. Otherwise, he pays a fixed fine.

That seems reasonable to me.
