Turn Left On Red

What are your views on the Turn Left On Red rule which is operating in some parts of the world?
I've always tended to agree it is a good thing to assist traffic flow but we're behind the times here and no government has ever wanted to introduce it, even for a trial.
It's where you have a red traffic control light facing you and you stop and then you are able to treat the red TCL as a Stop Sign and proceed by turning left providing it is safe and expedient to do so.
There is a disclaimer here though. Are our roads designed for it? By that I mean that you might get drivers who want to turn left on a red TCL but can't because the car in front wants to go straight ahead so has to remain stationary.
I guess that's no different though to green filter arrows now.
In left hand drive countries they obviously have Turn Right On Red rules.

In the US and Canada it is turn right on a red, except Quebec which has to be different. On the island of Montreal no turn right. But off Island its OK to turn right on a red light. It helps to keep the traffic flow going.

I hope we can catch up over here and do likewise.
