The leading front fender has right of way unless the other guy has is much bigger and then protect your own fender.
I know it's done in the Phils & here's Addis Ababa, where I was 2 years ago next month. Westerners just don't "get it" but it works.
Ah ok. Yes, I just never heard it called that before.
All these regional differences work until the traffic gets to critical, then it all turns to ratsh*t. There are various derivations throughout Asia as you say and it is best to try and blend in. However, blending in can exacerbate the situation towards a gridlock. A motoring correspondent here wrote an article about his 6hour journey to travel 1.5km last year.
I used to live in an area that was very congested on occasion. Basically a cut through of the largest homeowners' association in the world (?) where the committee decided to enforce sticker only entry, creating chaos. I was sitting in bumper/fender to bumper traffic in a block for about an hour with barely any movement. I got to the point where I could leave a junction clear and within 10 minutes the traffic was running smoothly again. Over the course of a week the same opening up of a junction had the same result. Filipinos block junctions 99% of the time.
There are instances where I "encourage" other road users to comply with priority*** by looking away from them but keeping them in my peripheral vision. Combined with no variation in speed, this invariably (though not always) encourages them to review their course of action and pause until I have passed, then pull out.
***I do not like the term "right of way" as "priorities" change, but crumple zones don't, especially when encountering your ''much bigger" road users
I will always say that places like the Philippines are a great training ground, as the potential situations that are taught in the UK, etc, are actual scenarios you can encounter on every journey here. Except perhaps the ex-US forces Subic area, where the driving "suddenly" improves due to continued "heavy manners" enforcement. If that is a leftover US legacy, which I think it is, thank you.
