I don't believe this.
Phils is jammed with traffic, but the drivers aren't THAT bad, there's just too many of them for a city to manage.
I've driven in South Africa, it's fine and there's even a road law regarding junctions where people emerge through a gentlemans agreement, you let someone out if you feel generous - it actually works. Granted this wasn't in J'Burg. Oh and don't stop your car in certain places because you'll be pulled out and probably killed, there's road signs in the worst places.
Much worse was Lebanon. Every single car had bumps and scratches, every car belched out fumes, every driver would pass on the right, the left - if there was a space, they'd try to use it, and if it meant SCRAPPPEEEEEE against another driver, then no worries
