Maybe OT, but I just came back from the Philippines. They seem to understand traffic there. On motorways you have big signs:
"Don't tailgate" at regular intervals. I wish to see this here.
Then big signs on gantries over the lanes: Over inner lane: "This lane is for busses and lorries" Over outer lane: "This lane is for overtaking only"
So middle lane is where to be; middle lane is the norm.
They also have 'seconds left' timing info on traffic lights, that reduces stress.
